Tanglefoot bag

From NWNWiki

A tanglefoot bag is a grenade-like weapon packed with stringy strands that burst on impact to snare a target. The round, small leather bag is full to bursting with an alchemical goo. Once exposed to air, the goo becomes tough and resilient, able to hold a creature in place for up to 2 rounds.

[edit] Special properties

• On-hit entangle: requires a reflex save, DC 15. If the target fails the save, it is entangled for 2 rounds.
