Overview
Flushmaster is a mid-chapter Sewers miniboss with modest personal stats but a unique environmental gimmick: instead of attacking your cats directly, it pushes them across the board toward hazardous tiles such as spiky rocks and ledges. The environment does Flushmaster’s killing for it. Teams that ignore tile awareness and rush in without a plan will lose cats to the map rather than to the boss itself.
Key Mechanics
Unit Push
Flushmaster’s primary ability is a forced repositioning push that moves targeted cats in a straight line. It specifically aims pushes toward visible hazards. A cat pushed into a spike tile takes damage. A cat pushed off a ledge or into a wall may take additional impact damage. Flushmaster does not deal much direct hit damage, so your cats will usually survive the push itself but potentially die to whatever is at the end of it.
Recommended Team Composition
Tanks are the best counter: high CON and HP means they can survive landing on a hazard tile, and pushing a tank toward spikes is much less punishing than pushing a Mage or Cleric. A second cat with a stun or anchor ability can prevent pushes entirely if timed correctly.
Step-by-Step Strategy
1. Before moving any cat in the opening turn, identify every hazard tile on the board. Spiky tiles are usually visually distinct. Ledges and water tiles are the other main hazards.
2. Position fragile cats (Mage, Cleric, Hunter) away from any clear push path toward hazards. Leave the hazard-adjacent positions open or occupied by your tank.
3. Use your tank to absorb pushes. If a push hits your tank into a spike, the damage is survivable. A Mage hit into a spike may die outright.
4. Focus fire on Flushmaster once your team is safely positioned. His personal stats are low enough that sustained ranged damage will finish the fight quickly once you have taken the environmental danger off the table.
Drops
Flushmaster can drop a Snack trinket and other minor items. As with all Sewers minibosses, the exact reward varies per run.
