The Sewer Dungeon is a dangerous, maze-like sewer complex filled with poisonous creatures, life-draining ghouls, and Mimics disguised as chests.

• Antidotes can prevent new Poison applications, but do not prevent Wither, direct damage, Slowness, or life-drain attacks.
• Plan for projectile pressure and creatures that heal themselves at close range.
• Keep enough hotbar space to fight and collect loot under the shared inventory rules.
• Do not assume every chest-shaped object is a normal dungeon treasure chest.

Health below is base health and can increase with difficulty.

• Life drain: Ghoul and Alghoul bites reach targets within 5 blocks. Red particles and sounds accompany damage and self-healing. Keep your distance when possible to avoid feeding their recovery.
• Spikes: red projectile trails mark incoming spikes. Move out of their paths, and remain alert after killing a SpikedGhoul because its death can trigger a wave.
• Poison pools: moss-like patches mark nearby poison hazards. Treat the area as a warning, not ordinary safe terrain.
• Mixed debuffs: Antidote does not block BlackOoze's Wither, Alghoul's slowing touch, or the Chuul's slow.

A Mimic chest is a chest-looking trap, separate from the ordinary treasure chests described on Provisions and Treasure Chests.

• Damaging the chest can release a Mimic after briefly debuffing nearby players.
• Interacting can trigger blindness, Slowness, and an armor-ignoring attack for 50% of your current health, then release the Mimic.
• The Mimic's bleed attack deals ten 2-damage pulses, while its close-range bite also heals it.

A Skeleton Key or Antidote does not disarm a Mimic. Its direct damage, bleed sequence, and slows are not Poison effects. These hazards are distinct from an ordinary chest's unkeyed poison trap.
