Toxin Pillar

A vertical pillar of sickly, toxic green rises from the ground at a location you specify. Each creature in a 10-foot-radius, 40-foot-tall cylinder centered on a point within range of the spell must make a Dexterity saving throw. It takes 6d6 antimonic damage and 6d6 intoxicating damage on a failure, or half as much on a success.

At Higher Levels. When you cast this spell by spending Mana points equal to an 8th-level spell or higher, the antimonic damage or the intoxicating damage increases by 2d6 for each level above 7th.
