You turn into a swarm of scurrying insects, held together by the power of your consciousness.

Prerequisite: You must have the wild shape power.

Effect: Until the end of the encounter, you can use wild shape to assume the form of a cloud of insects. In this form, you gain a fly speed equal to your speed, and you can hover. You also become insubstantial. When you squeeze, you can move at full speed instead of half speed and can fit through any opening large enough to accommodate even a single insect. You can't attack, pick up anything, or manipulate objects.
    Until this power ends, you can use wild shape to change among this form, another beast form, and your humanoid form.
