Strategy
Poisonous Vapours never misses and ignores AC, making it one of the stronger early game spells. The downside is that it relies on poison - damage is done over time, and cannot damage foes with poison resistance. If the enemy isn't in melee range yet, you can walk backwards so that the enemy takes poison damage while it chases you.

- In Tiles, you can count poison stacks by the number of green poison drops on the monster. 1 drop is 1 stack (poisoned), 2 drops is 2-3 stacks (very poisoned), and 3 drops is 4 stacks (extremely poisoned).

- Prior to 0.31, this spell was called Poisonous Vapours. It was a Poison Magic/Air spell, had full LOS range, but did not have a chance to weaken foes. Also, it inflicted
power/15stacks of poison, but with no bonus against non-poisoned foes. - Prior to 0.27, Poisonous Vapours would create a short lived cloud instead of inflicting poison directly.
