Cocoon

Description
Genji fires a ball of silk in an aimable arch, which will trap any enemy unit that it touches in a Cocoon. While Cocooned, enemies cannot attack or move, but they cannot be damaged either (except by the Jagra Eggs Lifesteal). Cocoon can't interrupt most abilities, but it will put them on "pause", meaning the skill will continue as normal once the Cocoon ends.

The ball of silk can bounce off walls, the ceiling and the edges of Platforms. It disappears as soon as it touches the ground, however.
