This greenish sack is sticky with sap.

A thorn pouch allows you to bring forth several types of magical plant effects for offensive and defensive purposes. A pouch has 5 charges, which are renewed each day at dawn. Spending 1 or more charges when you place your hand within the bag allows you to draw forth a single thorn that has one of the following effects (each as the spell of the same name, but with a duration of 9 rounds):
1 charge: Entangle.
3 charges: Spike growth.
5 charges: Wall of thorns.
To use a thorn after drawing it forth, you drop it into your own space or any adjacent square (a free action). After 1 round, the thorn produces the desired effect. If you don’t drop a thorn within 1 round after drawing it, it disappears with no effect.

Prerequisites: Craft Wondrous Item, entangle, spike growth, wall of thorns.
Cost to Create: 2,000 gp (plus 400 gp for base item), 160 XP, 4 days.
