Win conditions
Keep phase-1 summons under control so the board is open before pushing Rat King below 70 HP. Treat 70 HP as a real phase breakpoint and enter it with spacing, cooldowns, and a retreat lane. Use control or buff removal in phase 2 to limit the increased damage and speed while clearing Pinkies, Dips, and Poop.
Opener
- Clear the first Lil' Rats quickly and do not rush the 70 HP threshold on a crowded board.
Midfight
- Push Rat King toward the breakpoint only after the arena has enough space for the aggressive second phase.
Finisher
- Once phase 2 starts, prioritize board control and then end the fight before repeated Dash plus spawn turns rebuild the clutter.

Run killers
- Letting Lil' Rats occupy the board until Toss and Trample have too many collision targets.
- Entering the sub-70 HP phase with no room to dodge Dash or clear the new spawn set.
- Lining up multiple cats so one phase-2 Dash can hit and displace more than one important unit.
Positioning rules
- Avoid leaving adjacent collision targets where Toss can damage both the thrown cat and the landing target.
- Preserve straight escape lanes before the phase-2 Dash pattern begins.
- Spread the team so Dash and spawned bodies cannot lock several cats into one lane.
Loadout hints
