Feign Death

By means of this spell, the druid or any other creature whose levels of experience/hit dice do not exceed the druid’s own level can be put into a cataleptic state which is impossible to distinguish from actual death. Although the person/creature affected by the feign death spell can smell, hear, and know what is going on, no feeling or sight of any sort is possible; thus, any wounding or mistreatment of the body will not be felt and no reaction will occur and damage will be only one-half normal. In addition, paralysis, poison, or energy level drain will not affect the individual/creature under the influence of this spell, but poison injected or otherwise introduced into the body will become effective when the spell recipient is no longer under the influence of this spell, although a saving throw is permitted.
Note that only a willing individual can be affected by feign death. The druid is able to end the spell effects at any time desired, but it requires 1 full round for bodily functions to begin again. The material component is a piece of dead oak leaf (in addition to mistletoe, of course).
