The offtank picks up the
boss after a dribbling ichor has completed, and the main tank picks up the adds
– we will mark the location where the adds should be gathered.
The main tank picks up the boss once their debuff has cleared.
If the boss is <45% before a dribbling ichor begins, try to push the phase.
Otherwise stop DPS, collect and kill the adds, then push.
Hero once the boss has been interrupted downstairs.
Currently we ignore all adds (tank picks them up of course) and burn the boss
down.
