Nightmare is the climax of the Kanturu event line: an imposing boss that rewards teams who manage to advance all the phases.

Dica: Quick answer: Nightmare is unlocked at the end of the Kanturu event. Face it in an end-game group, taking extra care with its area attacks.

How to reach it

  1. The Kanturu event goes through phases (Ruins, Relics);
  2. The server collectively advances these phases;
  3. Once complete, Nightmare is unlocked for the encounter.
Nota: In many seasons, Kanturu connects to Crywolf: defending Crywolf keeps Kanturu access open.

Rewards

  • End-game Excellent and Ancient items;
  • Rare materials;
  • Prestige for the group that defeats it.

Strategy

  • Go in a balanced, well-geared group;
  • Watch the area attacks — spread out;
  • Keep the support alive to sustain the damage;
  • Know the attack pattern before committing the team.
Atenção: Underestimating Nightmare is a recipe for a wipe. Bring plenty of potions and assign roles in the team.
