Siegecrafter Blackfuse created the most ridiculous thing I’ve ever seen, the Shockwave Missile
Siegecrafter Blackfuse is the twelfth boss of the Siege of Orgrimmar raid, and the first boss of the Downfall wing of Flex/LFR difficulties. In this encounter, players must defeat Helix Blackfuse, who is piloting a pretty awesome mecha with a magnet-fist, a sawblade-hand, a laser tail, and a sinister missile face right in its chest. In other words, Goblin engineering, amirite?
The Blackfuse fight is a single-phase affair that’s all about execution, execution, execution. Compared to some of the earlier fights, it’s relatively low on mechanics, but the mechanics it does have are punishing enough that your raid will need to understand them and react properly in order to defeat the encounter. There is frequent target-switching, as players must deal with the boss, one frequently-spawning add with a high health pool and periods of damage vulnerability, and frequent waves of low-health but high-priority mines.
Every forty seconds or so, the raid will have to deal with a new combination of mechanics, as Siegecrafter rolls out a new set of weaponry from his Assembly Line. Players have some choice in which mechanics they will deal with, since the raid can send a team of DPS onto the Assembly Line to destroy one of the three weapons, removing it from the encounter briefly.
For healers, the damage pattern of this fight is variable based on how good your raid is at avoiding the avoidable damage and handling the mechanics. Tanks will take heavy damage throughout the fight, and one of the adds has an AoE attack that hurts more each time it’s used, which may require cooldowns to survive late in the fight. Other than these guaranteed sources of damage, the rest is avoidable, and players who don’t avoid it will take spiky, heavy damage. Your raid is likely to spread out, so gear and Talent accordingly.
