Venom Fog Technique

Kasekigumo expels a thick fog of poison around himself and anyone in the area. This poison is actually the venom he would normally secrete from his fangs. However, decades of decay have turned his venom glands to dust, causing new venom to instantly become a gas and escape from his body. The poison is not fast acting, nor potent, but is thick enough to hinder breathing and widespread enough to prevent a quick escape.

The foe will slowly be affected by the poison, with more damage being done the longer they remain in the area and the more fog they inhale.
