Half-Rat

Half-Rat is a rat-cat hybrid experiment found in The Lab with 10 HP, 5 damage, and 1 base movement. Its ChainDash attack is its defining ability: it launches a straight-line dash up to 10 tiles in a cardinal direction, and if that dash deals damage, it immediately triggers another dash to the left or right of its current facing. The chain can continue as long as each dash connects, letting it cover enormous distance and potentially hit multiple targets in sequence.

Each dash hit has a small chance to inflict a disease or disorder, which can accumulate across a full chain. Despite the frightening range of the attack, Half-Rat's AI doesn't pathfind optimally to maximize the chain — it often moves in ways that limit how many targets it can thread. Still, when it does line up a full chain, it can deal significant damage across multiple cats in a single action.

Half-Rat's low HP makes it easy to eliminate quickly with most builds. The key is not letting it get a free opening dash into a clustered group of cats, where even a suboptimal chain can chain across several of them. Spread your formation out to limit the number of potential chain targets, and prioritize it early in a fight to prevent its disease-spreading hits from accumulating. Its Champion form doubles the HP to 20 and adds 1 damage, requiring more dedicated focus to take down fast.
