Fight phases
- 1
Beam phase
Assign players to red (threat/health), green (healing done), and blue (damage/mana) beams and rotate them out before the stacking debuff gets lethal.
- 2
Banish phase
Netherspite periodically Banishes himself and portals spawn — reposition and reset for the next beam phase.
By role
Tanks
The red-beam tank holds aggro AND the beam; swap with a second tank before Perseverance stacks too high. Face the boss consistently so beams stay predictable.
Healers
The green-beam player is healing-boosted but takes a stacking debuff — rotate them and heal the beam-holders through their stacks.
DPS
Blue-beam holders do the damage; rotate them out before Void Zone stacks kill them. Discipline in beam rotation is the whole fight.
Common mistakes
- ✕Holding a beam too long and dying to the stacking debuff.
- ✕Letting a beam go unblocked, which empowers Netherspite.
