This will be a very short post in the Tsulongevity series, because I just want to bring it to everyone’s attention:
The dungeon journal for Heroic Tsulong does not accurately describe the behaviour of The Light of Day.
The dungeon journal claims that the +healing decays over time while the +mana increases over time. I have not found this to be true – it is a flat 16x healing boost and a flat 15,000 mana per second return.
I have a couple WoL snippets to share with you:
[22:48:03.656] RDruid afflicted by The Light of Day from RDruid
[22:48:04.423] RDruid Rejuvenation RDruid +260668 (O: 18958)
[22:48:04.424] RDruid casts Rejuvenation on RDruid
[22:48:04.424] RDruid Rejuvenation Tsulong +17477
[22:48:05.425] RDruid casts Rejuvenation on Tsulong
[22:48:05.495] RDruid Rejuvenation Tsulong +279626
[22:48:06.192] Unknown's Jade Spirit fades from RDruid
[22:48:06.421] RDruid Rejuvenation RDruid +*0* (O: 550176)
[22:48:06.421] RDruid casts Rejuvenation on RDruid
[22:48:07.443] RDruid casts Rejuvenation on Tsulong
[22:48:07.512] RDruid Rejuvenation Tsulong +267075
[22:48:07.912] RDruid's The Light of Day fades from RDruid
[22:48:07.912] RDruid afflicted by Bathed in Light from Tsulong
This WoL snippet shows my guild’s Resto Druid (name changed to protect his identity, just like on Unsolved Mysteries! *cue spooky music*) spamming Rejuvenation on himself and the boss under the effects of The Light of Day. I asked him to do this because Rejuvenation’s up-front heal is extremely consistent, so any variance in its healing dealt would be attributable to decay on the +healing component of The Light of Day, and with a 1-second GCD, it would provide a higher level of granularity than any other spell. (While Renew also has an up-front component if the Priest is Holy, this component does not benefit at all from The Light of Day, so it would not be useful.)
I deleted all the Rejuvenation ‘ticks’ except one, to show you what a Rejuvenation that is not buffed by The Light of Day would heal for – the entry in green above – the rest of these are the up-front heal associated with casting Rejuvenation.
As you can see, there is no evidence of decay over time. While, yes, the latter two heals are slightly smaller than the first two, this is wholly consistent with the RDruid in question losing his Jade Spirit buff. When I normalise for the loss of Jade Spirit, the four healing events in this log snippet are 15.9997, 15.9997, 16.0002, and 16.0002 times the amount of healing a non-The Day of Light-buffed Rejuvenation should deal. (The variance here is likely a rounding difference between the way I calculated RDruid’s spell power after losing Jade Spirit, and the way the game calculates it.)
Another point in favour of my no-decay theory is the behaviour of the mana restoration portion of The Light of Day. Again, the dungeon journal claims that the amount of mana it restores increases over time. However, this log of my guild’s Holy Paladin’s mana gains from The Light of Day begs to differ:
[23:13:21.508] HPally gains 15000 mana from HPally's The Light of Day
[23:13:22.514] HPally gains 15000 mana from HPally's The Light of Day
[23:13:23.479] HPally gains 15000 mana from HPally's The Light of Day
[23:13:24.488] HPally gains 15000 mana from HPally's The Light of Day
[23:13:25.485] HPally gains 15000 mana from HPally's The Light of Day
[23:13:26.525] HPally gains 15000 mana from HPally's The Light of Day
Once again, a flat rate of return.
Things to take away from these log snippets?
- There is no need to front-load your healing during The Light of Day. No matter when you cast a spell, as long as it is within that window, it will receive a 1500% boost.
- If you have the choice between talenting for more casts during The Light of Day, versus almost anything else, take the more-casts option. This is especially relevant to Resto Shaman; Elemental Mastery – even though it’s only useable on a single The Light of Day window – outperforms Ancestral Swiftness, because it enables an extra cast with a 1500% modifier.
- Note that when my RDruid buddy gained Bathed in Light, he lost The Light of Day. The buffs do not stack. Don’t try to stack them!
- What is probably best is to chain together The Light of Day and Bathed in Light back-to-back. Most throughput cooldowns last longer than 6 seconds – in fact, many are long enough to cover a full 12-second timeframe – so by doing this you will get extra power out of your cooldowns. Whether it is better for you to get TLoD then BiL, or BiL then TLoD, is really up to the specific cooldowns your class has.
I’ll be going back to revise my Druid strategy with these points in mind, and I should have a Shaman strategy soon!
