Warning Snakes

While the caster is under the effect of this spell, snakes will magically manifest to warn them of dangers. For example, snakes may crawl from behind an untrustworthy person, coil around a poisoned chalice, slither from the direction of an unseen assailant, or appear in a doorway leading to a trap. The snakes give no indication of how dire or immediate the danger is, nor can they convey any information about it through use of an ability or spell that would allow the caster to communicate with them (eg via Speak With Animals).

After an hour, snakes no longer appear, and any snakes that have manifested during the use of the spell will assume a normal nonmagical life.
