Dust of Sneezing and Choking

This fine dust appears to be dust of appearance. If cast into the air, it causes those within a 20-foot spread to fall into fits of sneezing and coughing. Those failing a DC 15 Fortitude save take 2d6 points of Constitution damage immediately. In addition, those failing a second DC 15 Fortitude save 1 minute later are dealt 1d6 points of Constitution damage. Those who succeed on either saving throw are nonetheless disabled by choking (treat as stunned) for 5d4 rounds.

Prerequisites: Craft Wondrous Item, poison.

Cost to Create: 1,200 gp, 96 XP, 3 days.
