Escort the white orb through each lane and kill or CC any enemies that touch it
Jump or dodge shockwaves (Mordremoth & Soo-Won phases only); always stack in green safe circles; spread out orange circle markers
Handle each Elder Dragon's unique attacks as they come (projectiles, beams, CCs); stay on the commander's tag
Cleave down giant summons quickly; use stability or stun breaks for fear and stomp attacks; avoid standing in their vomit AoE
When Primordus appears, dodge his massive chomp attack (instant down if hit)
Final phase: continue handling greens and other avoids; focus down remaining adds ASAP
