Hydaelyn

You conjure a swirling vortex of wind aether that tears at all creatures inside. The vortex forms in a 20-foot-radius, 40-foot-high cylinder centered on a point within range. When a creature enters the spell's area for the first time on a turn or starts its turn there, they must succeed on a Strength saving throw or take 3d6 thunder damage plus 3d6 slashing damage, and half as much damage on a success. The area affected by the vortex is considered difficult terrain. On each of your turns after you cast this spell, you can use a bonus action to move the vortex 60 feet in any direction. At Higher Levels: When you cast this spell using a spell slot of 6th level or higher, the thunder damage increases by 2d6 for each slot level above 5th.
