Flushmaster

The Flushmaster is one of two possible mini-bosses in The Sewers, a bloated, toilet-themed monstrosity controlled by a Dip parasite riding atop it. With 100 HP and the fastest movement of any mini-boss in the game (Movement 6 via Teleport), it repositions unpredictably after every attack. Its 0 damage stat is misleading — its Flush wave move can send entire parties crashing into lethal terrain.

Each round, The Flushmaster summons a massive wave in the direction it's facing, pushing all units until they collide with an obstacle or wall. It then teleports to a random position and reorients randomly. On defeat, the Dip rider drops off and continues fighting as a standalone melee combatant. The Flushmaster is permanently Wet, making it vulnerable to Electric damage and freezable by Ice attacks — a frozen Flushmaster cannot move or attack.

Position cats to avoid being flushed into spiked terrain — map awareness is critical. Ice attacks that can Freeze it every turn make this fight trivial, effectively immobilizing it permanently. Electric damage bypasses its Wet status for bonus damage. Cats with the Scatological trait will instantly kill The Flushmaster on contact. If Freeze isn't available, use slow cats with movement abilities like Cat-A-Pult or buffed with Marked to stay in control of the positioning game.
