Berserk: On heroic Difficult, the Bosses will enrage after 10 minutes of Combat.
This is council encounter consisting of 4 golem bosses with a shared HP pool of 32M. There will only be two entities moving and using skills at a time. When a new golem is activated the old one will be granted a shield. This is there to encourage the dps to switch targets.
Players can stack them for extra damage from incidental AOEs, tank cleave, etc. The bosses do not do any cleaves, stacking buffs, or crazy AoEs that punish the tanks for this strategy. When the fight starts, only one golem is active. It has 100 stored energy, which starts draining as soon as you pull. Once the energy hits 50, another golem will "wake up" and join the fight. Once the first golem reaches 0, it shuts down, and a new one spawns. This continues in a cycle until you kill the boss.
- A "stream" from the back wall to the next golem will show you which one is spawning next. Get ready to pick that one up once your golem reaches about 3 or 4 energy. You will know what golem to expect based on the color of the stream. Don't stand in poison clouds, and don't let the boss stand in whirlpools.
- When you see "Acquiring Target" go off, Magmatron's target is about to take a lot of damage. A helpful red beam points to whoever is being targeted. The tanks are eligible targets as well. Get ready with preventive healing/shielding. If you are running low on mana, stand in a whirlpool for some nice regen.
- Stand in the whirlpools for a buff. Don't stand in the poison clouds. Kill any slimes that spawn (they spawn 3 at a time (6 in 25-man) and you get a raid warning). If a slime is targeting you, kite it (especially if you are melee). They can be slowed so use whatever abilities are available to your raid. When a boss casts their "shield" ability (look for keywords Barrier, Shield, Shell, or Absorption) switch targets immediately, or bad things happen. Special note for melee: Your tank might get hit with the "Lightning Conductor" debuff. Watch out for this. If that happens, get away from the tank ASAP as they will be hitting you with a big aoe.
- Spread out as much as you can. Don't stand in the bad stuff, but do stand in the good stuff. If you are targeted by Magmatron's "Acquiring Target" spell, stand there and take it (use damage reduction cooldowns if you have them; it will save the healer a lot of trouble).
- Lord Victor Nefarius yells: Hmm... the Omnotron Defense System. Centuries ago these constructs were considered the Dwarves' greatest tactical achievements. With so many counters to each construct's attacks, I'll have to rectify these designs for them to provide me any entertainment.
