Big Ball of Wax

Here is another installment of exTRAPaganza, our Thursday over-the-top trap series. 

At the top of the stairs is a giant ball of wax. This wax ball is activated by a stair near the top. It falls out of the ceiling and rolls down the stairs.

Targets on the stairs must make a hard Dexterity saving throw or be hit by the wax. It does no damage, but targets that fail the saving throw become entangled with the wax, and roll down with it to the base of the stairs.

At the base of the stairs are several torches. These ignite the wax ball.

Targets stuck in the wax take heavy fire damage, and then take light fire damage for 1d4 rounds afterwards.

Target not in the wax ball, but within 15 feet take moderate fire damage, with a moderate Dexterity saving throw halving this damage.
