Controlled Disintegration is a skill in the Physicist skill tree.
When a mouse dies, it leaves a small spring-like electrical arc on which your shaman and other mice can bounce. The arc only spawns up to the edges of the screen and will not appear off-screen.
This skill can make the mice more prone to rushing.
When bouncing on two electrical arcs close to each other or overlapping each other, you will spring much higher than just bouncing on one arc.
