Boss and mechanic notes

The Dead Ends has local boss notes for: Caustic Grebuloff, Peacekeeper, The Last Mercy: Ra-la. These notes are pulled from the local wiki and should be treated as source-backed prep unless separately marked as human-reviewed strategy.

• Miasmata: Roomwide AoE that additionally spawns AoE circles around the arena. These AoEs will move across the arena in the direction of the wind, so players must position themselves to avoid them. If hit, a player will receive the Necrosis debuff, which must be cleansed with Esuna or The Warden's Paean, or it will kill them if the debuff timer expires.
• Cough Up: Drops 3 sets of AoEs on each player, spread apart to avoid overlapping. After the AoE circles players will receive a red arrow above their head and the Craven Companionship debuff. Players must be stacked when the debuff timer expires or they will be inflicted with Hysteria for several seconds.
• Wave of Nausea: A telegraphed donut AoE around the boss. Being hit will inflict Necrosis.
• Pox Flail: Tankbuster.
• Blighted Water: Stack marker.
• Befoulment: Targeted AoE circles, spread to avoid overlap.
• Decimation: Raid-wide AoE that also covers the outer part of the arena in fire. Contacting it will inflict Burns, dealing damage-over-time.
• Electromagnetic Repellant: The boss summons a field that fills its hitbox, that debuffs players with Electrocution and deals damage as long as they stand in it.
• Order To Fire: Spawns a number of turrets around the boss, which then shoot line AoEs directly outward from the boss. The line AoEs converge at the edge of the boss's hitbox, leaving narrow cone safe-zones between the line AoEs between the boss's hitbox and the edge of the arena. Usually combined with a targeted AoE, so spread to avoid overlapping.
• No Future: Spawns a pattern of targeting circles, which will hit every area of the arena at some point. Stand in areas that don't yet have targeting circles, or ones that spawned later, then move into ones that just exploded. This attack has two patterns: the AoEs will spawn under the boss and move outwards, or will start from outside the arena and move inwards. The hitbox under the boss is never a safe zone, so players should avoid standing there. If the AoEs spawn from the edge inward, players can identify the safe space and move into it. If they spawn from the center of the arena, players can stand at the point where the AoEs overlap, as the next ones to spawn will spawn outward from the first and not be touching. The attack will fire two sets of circles on the first time, and three sets per cast from the second cast onward. Each successive cast is rotated such that the areas that were initially safe in the prior cast are now targeting circles, requiring players to adjust their positioning.
• Peacefire: Spawns AoEs that will keep rotating around the boss, avoid by rotating with the AoEs. Always cast alongside Electromagnetic Repellant, forcing players to stand in the area the circles rotate through. This can be cast alongside Order To Fire, requiring the players to find a position ahead of the rotating AoEs and within the narrow cone safe zones.
• Eclipsing Exhaust: Spawns AoE circles around the edges, with several gaps between them, then triggers a telegraphed knockback from the center of the room. Get knocked into a gap.
• Elimination: Tankbuster. The boss fires a wide beam that will hit other players if they are too close, almost certainly killing them.
• Warm Glow: Raid-wide AoE.

Verification boundary

This page is generated from local TJPedia wiki data. It does not invent missing mechanics, NPC coordinates, loot tables, or current-party-finder strategies. High-end positioning and current-prog tactics still need human review before being labeled as a full strategy guide.

• Source-backed: duty facts, local boss notes, achievements, and music.
• Needs human review: exact high-end progression strategy.
• Use official patch notes for changed requirements or rewards.
