Tanglefoot bag

A tanglefoot bag is a grenade-like thrown weapon made of a round, small leather bag which is full to bursting with an alchemical goo. Once this goo is exposed to air, it becomes tough and resilient, able to hold the target creature in place where it stands.

The effect is subject to a DC15 reflex save. If the save is failed, the target is entangled and held in place for two rounds.
