“Chaos Theory” & “Split Personality”
Split Personality is the simpler to deal with but will require dps control and monitoring of relative health of all three adds (name plates will help here). Blow down all three of the adds within 5 seconds of each other on both splits.
Chaos Theory is more difficult to describe but I think is easier to achieve. Firstly we need to clear the lower area of all trash as we’re likely to be kiting him around a fair bit (how long depends on boss dps). This is going to be hard on the healer.
It’s a dps race and a positioning job.
The boss is pulled and maximum dps is loaded onto him, ignore all rifts, this is where things get interesting with the number of adds we’re going to be dealing with. I would reckon we ignore the adds (other than keeping the healer clear) until he shields. Probably stacking the healer on the tank / melee is going to make life a little easier for picking them up.
When he shields everyone backs off, the tank keeps “close” to the boss, probably the top of the ramp, and everyone else (including melee) pulls back to at least 15 yards from the tank. The lighting from the rifts is a chain effect, so if the tank is taking them and melee is within 15 yards of the tank they’ll get clobbered as well.
The tank will attempt to collect the adds but will not run back to the healer to clear them, that’s a job for the dps. When he unshields (45 seconds) he’s tanked in the new position, with dps focusing on the boss.
This process repeats with the party working back down the ramps to the base level and then around the area until he’s dead.
