Passive

A string slime can feel nearby motion through vibration and air movement.

Split

Passive

Whenever a string slime would take slashing damage (if it weren't immune) and has at least 10 HP, it splits into two identical slimes with half the original's HP. One string slime is in the same space as the original, and the other appears in an adjacent unoccupied space. If no adjacent space is unoccupied, move smaller creatures and objects out of the way to make a space or the split is canceled at the GM's discretion.
