Wetzel Wax

You hurl a glob of wax. Choose one or two creatures you can see within range. If you choose two, they must be within 5 feet of each other. A target must succeed on a Dexterity saving throw or take 1d10 fire damage.

A creature who fails must take an action or bonus action on their next turn to remove the wax before it hardens. If they do not they are restrained at the end of their turn and must make strength save equal to your spell save DC.
