Cloudkill

A poisonous fog streams from the caster’s fingertips, filling a 30′ diameter area in front of the caster.

Movement: The fog moves at Speed 10, driven by the wind or, in still conditions, away from the caster.

Sinking: Because the fog is denser than air, it sinks to the lowest point, flowing down hills, into holes, and so forth.

Damage: All creatures in contact with the fog suffer 1 damage per Round.

Creatures of Level 4 or lower: Must also Save Versus Doom (once per Round of contact) or die.
