Creeping Doom

Description
The druid summons masses of flying insects, one swarm per two caster levels, that attack targets at random in the affected area. Swarms have a base attack bonus of +6 (with an additional to hit bonus based on the caster's Wisdom x 2) and do 2d6 points of damage when they hit. Swarms last for three rounds before dissipating. Creeping doom stacks with itself - if the druid casts this spell again while swarms still exist, the new swarms will join the existing swarms in attacking their targets.
