The Watcher is the boss of Chapter 3, a unique challenge that requires you to deal with constantly respawning 'Eyes' before you can damage the main boss. This fight emphasizes burst damage and crowd control.

Abilities:
- Summon Eyes: Summons multiple 'Eyes' that attack and apply debuffs. The Watcher is immune to damage while Eyes are alive.
- Eye Respawn: Eyes will respawn after a short delay once defeated.
Strategy:
- High Burst/AoE: You need to quickly clear the Eyes to create damage windows on the Watcher. Warrior's 'Damage to All' or Necromancer's skeleton swarm are ideal.
- Attack Speed: Crucial for all classes to clear Eyes efficiently.
- Sustained Survivability: The fight can be prolonged due to Eye respawns, so good HP, defense, and regeneration are important.
- Potion Management: Save potions for when you're actively damaging the Watcher.
- Debuff Resistance: Some Eyes apply debuffs; consider items that mitigate these if possible.
The key is to find a rhythm of clearing Eyes, damaging the Watcher, and surviving the onslaught.
