Wax Tomb

You point at a Medium or smaller creature you can see within range, causing a torrent of molten wax to pour over it. The creature must succeed on a Strength saving throw or have its speed reduced to 0 feet. A creature that fails the saving throw by 5 or more is also restrained for the duration. A creature affected by this spell, or a creature within 5 feet of it, can use its action to make a Strength check against your spell save DC, freeing the affected creature and ending the spell on a success.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the maximum size of creature you can target increases by one category, from Medium to Large, for example, for every two slot levels above 1st.
