|Turns the air around a targeted creature poisonous. Exceedingly little poison is created, generally just enough to poison the target before dispersing.|
Poisonous Vapours is a level 2 Poison/Air spell which attempts to place a poison cloud on an enemy in line of sight, and is therefore smite-targeted. At low spell power, the cloud itself may not be visible, but the poison will nevertheless be stacked on the enemy.
Poisonous Vapours will fail to cast if:
- There is a non-poison cloud on the creature (this includes Mephitic Cloud), or
- The monster has poison resistance. This includes monsters wearing rings or armour that offer poison resistance. It is possible to partly identify equipment in this way.
Poisonous Vapours is an excellent spell for Venom Mages to pick up at XL 2, as a much more reliable, more damaging Sting. The fact that it is level 2 and can't miss also makes it appealing for any character with a few free spell levels.
If a monster is already standing in a dangerous cloud, they generally disregard further clouds in order to close in on you. You can make use of this by placing effects from Conjure Flame, Freezing Cloud, or a wand of clouds and then prompting cautious monsters to walk into them by using Poisonous Vapours on them.
