Tynnu (Valefor)

You mark a surface within range with a 15 foot radius forming vortex, then select a point in initiative where the vortex collapses. When this vortex collapses, all creatures within 30 feet of the radius must succeed on a Strength saving throw or be pulled into the center. If a creature is already within the radius when the vortex collapses, they automatically fail this saving throw and take 3d10 force damage.

At Higher Levels
The damage of this spell is increased by 1d10 for every spell slot spent above 5th.
