Support gem suggestion: Skittering Swarm Support

Skittering Swarm Support would be a support gem for traps/mines/minions.

Summon a number of robotic minions [Skitterbits perhaps] who carry a secret payload of the supported trap/mine skill.

Trap skitterbits attack once and then die, triggering their trap payload.
Mine skitterbits attack continuously until the player detonates mines,
sequentially killing and detonating their skitterbit mines.
