Combat

Alchemist

Create an tanglefoot bag which immobilizes an opponent.

Craft DC: 25

You create an alchemical stone that can be used as a ranged attack with a range increment of 10 ft. When it strikes a hard surface (or is struck hard), it creates a deafening bang that is treated as a sonic attack. Each creature within a 10-ft.-radius spread must make a Fortitude save or be deafened for 1 hour.

You can increase the Craft DC for this item in increments of 10; each time you do so you increase the duration of this ability by 1 hour, add 1d6 sonic damage to all creatures within the effect’s radius (creatures who pass their saving throw against this item take half damage), and increase the radius of the effect by 10 ft.
