Viscous Vortex

A green downpour of slime falls in a 20-foot-radius, 60-foot-high cylinder centred on a point within range. Until the spell ends, vision is lightly obscured the cylinder.

When a creature enters the spell’s area for the first time on a turn or starts its turn there, it is subjected to the tempest of viscous slime that cause searing pain, and it must make a Dexterity saving throw. It takes 10d6 Acid damage on a failed save and is Restrained, or half as much damage and is not restrained on a successful one.

At the beginning of a creatures turn it may make a Strength saving throw to break free from the slimes grasp.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 2d6 for each slot level above 6th.
