This is just a pretty quick post to talk briefly about the trinket drops collectively known as “Amplification trinkets” that we’ll see in 5.4. As usual in WoW, the tooltip doesn’t tell the whole story, so I’m here to fill in the blanks. I’ll try to keep the math to a minimum in this one, but some of it will be unavoidable, sorry ;)

The Amplification trinkets have two passive abilities, but the important/interesting one is the effect that improves your Spirit, Haste Rating, and Mastery Rating values and adds to your Critical Strike bonus.

Before I get into the nitty-gritty of how to evaluate the raw stats that this trinket grants you, I’d like to first address something that is a bit … *flawed* … about this trinket’s tooltip.

**The tooltip rounds the % Amplification effect off to the nearest whole number, while the benefit you get from equipping the trinket is not rounded.**

What this means is that you’re rarely going to see your in-game results match what the trinket’s tooltip claims. I’ve compiled a table, to the right here, of the various iLevels of this trinket, the benefit the tooltip states, and the approximate benefit you’ll get.

(Note: These numbers vary slightly from in-game data at the third decimal point, meaning they don’t show any differences at all until you have over 100,000 rating in one of the affected stats. Any variation you see in-game is due to the game’s rounding mechanism. Still, if you are worried you might hit that 100k mark, the item-budget-derived values can be found in this post on HowtoPriest. Note that neither this model nor my model can predict exactly how the game is going to round your final values, but in either case you should be off by no more than 1 rating.)

This information is really only *important* if you ever want to do your own calculations for things like, “How much larger will my Critical Strike heals be with my 2/2 upgraded Warforged trinket?”, but from an informational standpoint I think it’s pretty important to realise that the tooltip is a bit misleading, and I hope this helps at least *someone*! :)

The way this works is pretty simple – whatever *Rating* you have in Haste or Mastery, and whatever amount of Spirit you have, gets multiplied by (1 + whatever the “actual %” for your trinket’s iLvl is). So if you have the Normal mode Prismatic Prison of Pride, your Haste, Mastery, and Spirit all get multiplied by 1.07. Depending on how much of those you have already, this can be anywhere from a 100- to 1300-Rating boost to your secondary stats.

I’ll note here also that * the Amplification trinket also increases the Spirit you receive from Mana Tide Totem.* Even if the casting Shaman doesn’t have the trinket, players who have the Amplification trinket equipped will receive +214% of the casting Shaman’s Spirit, rather than 200%. (So if your Shaman has 100 Spirit, you will get 214 Spirit from their Mana Tide Totem. If your Shaman also has the Amplification trinket, you will get 228 Spirit from their Mana Tide Totem.) Similarly, the Amplification trinket also increases the amount of Spirit you get from trinket procs/on-use effects, even though this is not accurately reflected in the tooltip of the proc/on-use buff.

It’s a little more tricky for Crit, and I will have to walk you through some math to explain my point:

First of all, **this trinket does not act like the “3% increased Critical effect” meta gem.**** **This is tripping a lot of people up, and maybe it’s a mistake on Blizzard’s behalf in wording it this way, but what the trinket does is an ** additive** 7% additional healing when your heal crits. It is not 2*(1.07X) = 2.14X. It is (2+0.07)*X = 2.07X. So if your heal normally hits for 100, and would normally crit for 200, then with the Amplification trinket, your heal will crit for 207.

Now then, with that out of the way, let’s talk about how to evaluate this effect in terms of secondary stat equivalencies!

Let’s say that you have a 25% chance to Crit in your gear. Without the trinket, your average heal throughout the course of a fight would be:

`25% chance at 2X + 75% chance at X`

0.25*2X + 0.75*X

0.5*X + 0.75*X

1.25*X

Which you’ll notice is (1+Crit chance)*Heal Size.

With the trinket, your average heal would be:

`25% chance at 2.07*X + 75% chance at X`

0.25*2.07*X + 0.75*X

0.5175*X + 0.75*X

1.2675*X

Which you’ll notice is (1+(1.07*Crit chance))*Heal Size.

We can then translate our expected benefit from this additional Crit bonus into an *equivalent Critical Strike Rating*, and it’s much larger than what you’d expect. We had to do this math because we can’t just generalise directly to a 7% increase in the Crit Rating from our gear, like we can with Haste, Mastery, or Spirit. At our item levels, a fair portion of our Crit – around 10% Crit chance, in fact – arises from our Intellect-to-Crit conversion. Thus, while we have 25% Crit, only 15% of that comes from our gear, so a 7% boost to Critical Strike Rating from gear would only be worth 630 Rating.

What the trinket in fact provides is the equivalent of 0.07*25% = 1.7% additional Crit, and at a conversion of 600 Crit Rating to 1% Crit, this is **the equivalent of 1050 Crit Rating**. The more Crit chance you have, of course, the stronger this bonus is:

Now of course, putting more of your secondary stats into Crit reduces the number of secondary stats you have in Mastery, Haste, or Spirit, so this isn’t completely cheaty. But in general, the Amplification trinket is budgeted a little higher than it seems, and the more Crit you typically run for your spec, the more valuable this Crit bonus inflation will be.

Just as a basic idea, the normal t16 4pc + Warforged offset gear profile I built for my Shaman calculations (see previous post) has around 33k secondary stats, so this trinket is worth *at least* 2310 secondary stats (but more like 2900 if I factor in the Crit rating equivalence as I did above). Remember, though, that this “extra Crit rating” is *just a way of thinking about the trinket’s value*. It is not fair to count it against certain on-crit mechanics like Resurgence or Mana Tea, but this does work adequately for other mechanics like Ancestral Awakening and Living Seed if you are trying to model those.

The healing Amplification trinket now procs from Atonement heals as well as direct heals, although as far as I could tell – after minutes of spamming PW:S and Spirit Shell – it doesn’t proc from pure absorb spells. This makes the trinket perhaps a little harder to proc as a Disc Priest than as any other healing class, although so long as you remember to Holy Fire/Solace, Penance, and PoM on CD, you should be able to proc it even in the midst of PW:S spam.

It can be difficult for you to evaluate whether the trinket is performing properly on the Crit bonus front, because of the funky way your Crits work. Let me just throw some numbers at you to reassure you that you *are* getting the benefit you should expect to see, even if it doesn’t seem that way.

Let’s say you were a Holy Priest, and you cast Renew, and it ticked for 8444 non-crit. With the Amplification trinket, the crit would be 17479, and 17479/8444 = 2.07. As expected.

Now you swap back to Disc spec, and you cast Renew – just because it does the same exact healing every time, so it’s much easier to test with. Let’s surmise that *you have zero Mastery whatsoever*, just because Mastery screws with the analysis so badly. (I’ll come back and add Mastery in a later step for extra convincing.)

Without the trinket, your Renew healing would look like:

Non-crit: 8444

Crit heal: 8444

Divine Aegis: 8444

Total crit healing: 16888

Now, equipping the trinket:

Non-crit: 8444

Crit heal: 8739 (8739/8444 = 1.035)

Divine Aegis: 8739 (8739/8444 = 1.035)

Total crit healing: 17478

Notice that 17478/8444 = 2.07, just like you got from the Holy thought experiment.

Mastery confounds this a fair bit, but let’s have a look again, taking it into effect and assuming 30% Mastery:

No-trinket numbers…

Non-crit: 8444

Crit heal: 8444

Divine Aegis: 10977

Total crit healing: 19421

Trinket numbers…

Non-crit: 8444

Crit heal: 8739 (8739/8444 = 1.035)

Divine Aegis: 11360 (11360/10977 = 1.035)

Total crit healing: 20099

So you can see you’re still getting the 3.5% benefit on both the Crit heal and the Divine Aegis amount, just as we did before. It’s just harder to compare the Crit healing total to the non-crit amount because Mastery slides in and wrecks all your numbers. But you’re getting the same exact benefit from it all, I promise :)

The Amplification trinket is very strong for Disc, partially because the other trinkets with cool effects this tier – Nazgrim’s Burnished Insignia (Multistrike) and Thok’s Acid-Grooved Tooth (Cleave) – do not interact with Divine Aegis at all. Meanwhile, the Amp trinket buffs the size of your DA shields in two ways – via the Critical Strike bonus buff and the Mastery you gain by equipping it. You’re likely to want to run Prismatic Prison of Pride along with the Dysmorphic Samophlange of Discontinuity.

*Two Amps Better Than One?*

Before we dig into class specifics, I do want to note that equipping two Amplification trinkets does not give you some sort of multiplicative 14.49% benefit – just the additive 14% to all your stats. The second Amplification trinket isn’t, therefore, better than the first; they’re both equivalent.

**Currently, Mistweaver Monks are the only healer class that is able to proc the Intellect effect on both the healer and caster Amplification trinket through their usual healing mechanics.**** **The caster Amp trinket (shown, right) will proc for Mistweavers from their melee spells (Jab, Tiger Palm, Blackout Kick), Crackling Jade Lightning, Level 30 Talents, Spinning Crane Kick/Rushing Jade Wind, and Chi Torpedo. Since Mistweavers frequently use at least some subset of these spells during the course of a fight, double Amp trinket is quite strong for them.

Restoration Druids and Discipline Priests are also able to proc the caster Amplification trinket, but they have to go through some unusual hoops to do so. For Druids, the trinket will only proc from attacks in Cat or Bear form (including casting Faerie Fire), and for Disc Priests, the trinket only procs from auto-attacks. While you *could* in theory use these rarely-used abilities to force the trinket to proc *when you want it**, *giving you a large Intellect boost on-demand for your throughput CDs, you’re most definitely sacrificing positional and responsiveness advantages in order to be able to get the proc, and I’m not sure it’s strictly worth it, especially when the trinket could go to a caster DPS instead. **For most classes, the second Amplification trinket’s passive effect is probably not going to contribute more to your throughput than a trinket for which both the passive and proc effects are useful.**

Double Amplification trinkets probably *are* the best-in-slot combination for Mistwweavers, though. While both the Cleave and Multistrike trinkets have a nice proc rate for Monks due to the sheer volume of eligible healing events the Monk creates every second, they are lackluster compared to 14% larger Critical heals since Monks typically run very high Crit chance builds. The pair of trinkets can also help ease the burden of reaching the 50% Haste breakpoint – if you so desire, of course, which I am iffy on (see here for why, although I think there are a few extra factors that we could consider to expand the analysis).

Unfortunately, Monks are not able to coin the caster DPS Amplification trinket. It doesn’t show up on the loot table for any of the 3 Monk specs in the Dungeon Journal filter, so you’ll be ineligible for LFR/Flex versions, and will probably have to wait until all your casters have their trinkets before you’ll get a chance to play with the double-Amp setup. Fortunately, ’til then, the Cleave trinket is also quite nice. :)

Ask Mr Robot mods would love that detailed chart for the amp trinkets if they don’t already have that info.

Don’t know if you’ve used AMR lately but I love the customization of it.

In the last few months they’ve added haste breakpoints for all spells.

They’re working on an add-on to allow 1-click reforging from your imported profile.

Using this amp trinket will make haste breakpoints more tricky to calculate for optimal reforging.

It will also make AMR even more mandatory from an ease-of-use standpoint.

Thank you for this post.

I’m not a real power-user of AMR, I’ve only used it to build generic profiles for calculations here on the blog, but that sounds pretty handy.

Yes, the Amp trinket may make things a little more tricky for haste breakpoint calculations, though I’m hoping that any in-game reforge optimisation mods like the new AMR mod (?) and ReforgeLite will be able to do this intelligently. I haven’t really been able to test that on PTR since my computer pretty much dies every time I load a mod there, but I think it works out all right with Mistweavers and their Haste stance, so it should be able to catch anything that modifies Haste on your character sheet (which the Amp trinket does).

Oh, and I’m pretty sure Zoopercat has access to the same information I used to build that chart, but if you are in contact with them feel free to pass it on :)

Hey — I’m the main developer at askmrobot.com, and I’ve actually just started working on these amplification trinkets. They are a massive headache!

I figured the actual multipliers were scaling more finely with ilvl, took me a while to dig out the actual value… the raw data is kind of beastly to poke through for procs/spells.

One thing I’m not sure of yet is whether it multiplies the mastery raid buff or not… one would assume so, because it’s a rating buff. But then again, a trinket like rune of re-origination is based off of your rating but NOT including the raid buff. So the only way to find out would be to equip one of these trinkets with the mastery buff and find out (unless someone already knows).

Well you are in luck – as a Shaman I can’t *not* have the Mastery buff active! It multiplies Mastery raid buff :-)

Good to know! I’ll code that in.

I wonder if the amplification effect can stack if you have two of them equipped… like a healer and dps version. And how it stacks… multiplies? I would assume that this would not be useful in most cases, but maybe a disc priest or a mistweaver could get use out of two of them at the same time…

I addressed this, but kinda buried it in the “Monky Business” section of my post. As of right now on PTR, only Mistweavers get the full benefit out of both the Caster and Healer versions (anyone can obviously wear both, but other classes will be missing out on the Int proc, which is honestly a significant loss).

The two trinkets are not multiplicative, so wearing 2 gives you a 14% boost to stats, not a multiplicative 14.49% :)

I knew that I read that somewhere about a mistweaver being able to get full benefit of both… of course it was in the blog post that I’m commenting on, doh! Things are a bit crazy here in our last minute scrambling to get as good estimates as we can for all the new gear, so I get a little scattered.

You seem to know a lot about these particular trinkets, here’s one last tidbit that I can’t seem to find anywhere: whether amplification multiplies your base spirit (similar to how the human racial multiplies base spirit… which is actually a bit weird). I would assume yes… but I know that I will have an angry shadow priest who is 3 hit under the cap knocking on my door if I get that one wrong…

The way the human 3% spirit racial works is:

floor( [base spirit] * 1.03) +

floor( [all your other spirit] * 1.03)

I’m wondering if amplification works the same way… or if it’s just another multiplier on “all your other spirit”, and I would assume it multiplies with the human racial… but not sure on that.

This also makes me wonder if amplification rounds or floors to get the final rating amount for all 3 stats… but that’s really hard to figure out without some actual data.

Hi, impressed by your roundup, I actually took a lot time reading your site:)

Just to confirm, about the amplification trinkets, you sure that disc priest wont proc O.o, As I asked my guildie, he says both trinket proc on PTR.

And another question, I m planning to get the amp trinket for my shaman, but still hesitate about the 2nd one. According to my info from ptr, the cleave proc is actually quite low. And u said it quite nice. So probably there s something I missed. Do you have any suggestion ?

THANKS xD

It really depends on when your guildie tested it. Earlier in the PTR cycle, the caster DPS trinket did proc for Disc Priests; however, I tested it the day I wrote this article – very late in the patch cycle – and it did not. I spent 12 minutes casting nothing but Smite, and no procs; I then spent an equivalent amount of time casting the pure DPS spells (SW:P, Mind Sear, SW:D, you know, ones that don’t do atonement) and still couldn’t get it to proc. Even when it was the only trinket I was wearing.

It’s difficult to say now for sure because, less than one week in, hardly anyone has the caster DPS trinket yet. I’ll see if I can find a shadow priest with it and get them to go disc for me to test again.

The Cleave trinket’s gone through a few iterations, but it’s been solidly around 3% of my healing done on Garrosh this week (I won it off Thok of course, and didn’t use it on Paragons since it’s a terrible fight for cleave/short-range AoE abilities ugh) and for a trinket I am pretty happy with that. I kind of consider the Amp trinket a regen trinket since it provides a fair whack of constant Spirit, so was looking for a throughput trinket to pair with it. If you feel like you need more throughput, the Dysmorphic Samophlange from Siegecrafter (Int, with a huge Spirit proc that decays overtime) is a solid choice, and I’ll be chasing that too for fights where Cleave just won’t be handy.

Thx for the reply, pretty much what I thought, just the siege trinket is really boring :P

Totally. But these days, we get interestingness from our cloaks and meta gems :-D

Pingback: 5.4 Healing Trinkets | Azeroth Life

Have any mistweaver tested if both trinket still stack as in 14% healing, and will both trinket (dps and Healing) still proc for a mistweaver?

This is very difficult to test on live servers of course, so I doubt it, but I will keep an ear out :-)

Hi Dedralie,

Fantastic post as always. I’ve not been able to find the answer to this, so I thought I’d check with you – does the increase in spirit from the Amp trinket count towards Mana Tide Totem? I assume it did, but wanted someone else’s opinion as I’ve not had a chance to test it yet..

This ended up being a more interesting question than I had expected!

Yes, the additional Spirit affects MTT. And you get more Spirit than I would have anticipated this way.

Okay, so wearing the trinket I have 11969 Spirit. I expected Mana Tide Totem to give me an additional 200%, so an additional 23938 Spirit, bringing my total up to 35907 Spirit.

In fact, it gave me an additional 214% Spirit, bringing my total up to 37852 Spirit.

That’s pretty cool! So thanks for asking :)

The more I hear about this trinket, the more OP I think it is!

Cheers for investigating this and I’m glad my question piqued your interest. :)

I should note, for others reading this — well, I really should edit this info in to this post, perhaps? — that only the Shaman gets that extra 14% Spirit under MTT. So I have 11969 Spirit, MTT gives everyone else in my raid +23938 Spirit as expected, but gives me +25613 Spirit because I am the holder of the Amp trinket.

I guess those players who *also* have the Amp trinket would also get +25613, but I can’t confirm that.

You wrote that your numbers vary slightly from in-game data at the third decimal point. Could that be caused by scaling the percentage with a base itemlevel of 463 instead of 553? I’ve found a spreadsheet that uses 553 as the base item level and that sometimes results in a different third decimal point: http://bit.ly/1a1Ucx1

Nah, scaling from 463 or 553 doesn’t change anything and the 3.0267 number for the 463 version is straight from the game data.

The difference is that the exponential formula is an approximation of the game’s item budget calculations. The guy at How to Priest has access to the actual table of values that Blizzard draws from to determine stats on gear because he works on SimCraft, which includes that data. I don’t have access to that level of information so the estimate is the best I could do :-)

As a discipline priest I have both amplification trinkets and they DO both proc off of Smite/Penance/HF. (Titanic Restoration & Extravagant Vision)

Great to see my SP jump from 45k to 75k when it all proc at the same time :)

oups, I am sorry, the other on is [Frenzied Crystal of Rage], my bad.

Haha, glad you posted this; I was about to go write a strongly-worded letter to the devs XD

One never seen the immerseus one proc unless I auto attack which is not a suggestable thing to do with discipline priests…I am Indeed curious to see is they really do stack amp %s

Reblogged this on Disziplin Priester in 5.4 and commented:

Lohnt sich denn ein DD Amp. Trinket auch für einen Disc Priest?
