The user blows a cloud of thick black ashes. On the round that it is used, the technique fills a 15-ft. wide, 5-ft. tall area filled with smoke. On the second round, the cloud spread to 20-ft. wide and 5-ft high and will not spread further afterwards. Character moving through the ashes, or being caught in the cloud, must make a Fortitude save each round to avoid being blinded for 1d4 rounds. On the first round, characters caught in the cloud suffer 25 points of fire damage, damage which is reduced to 15 on the second round and to nil on the third round (damage does not set fire to combustibles and does not harm unattended objects).

It disperses after 3 posts, though a moderate wind (11+ mph) disperses the smoke in 2 posts and a strong wind (21+ mph) disperses it in 1 post.

Characters caught in a cloud of smoke must make a Constitution check (DC 10, +1 per consecutive checks) to avoid spending the post coughing and hacking and taking no actions; characters spending 2 consecutive posts coughing take 15 points of damage. A wet cloth held over the eyes, nose, and mouth provides a +2 bonus on the check, and a gas mask prevents requiring one. Smoke grants a 20% miss chance penalty to all those within.
