Wax Geyser

At a point you can see within range, you cause a geyser of hot wax to spring forth from the ground, covering a 10ft circle. Creatures within the 10ft circle must make a dexterity saving throw or take 2d8 fire damage and become restrained from the hardening wax. If they succeed, they instead take half damage and aren't restrained. At the start of an affected creatures turn, they can make a strength saving throw vs your spell save dc in order to break free. Huge or larger creatures cannot be restrained by this spell.

Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot above 1st.
