You could make the burning Abyss level deal fire damage per round/turn/whatever beat timing.
And because certainly our 363th layer looks like a BBQ!One description of the Abyss presents it as a region of intense, extreme, and unforgiving climates, with layers consisting of overwhelmingly fierce desert sandstorms; explosively unstable volcanic activity, boiling lava, and molten rock; blinding, sub-zero Arctic glaciers; bottomless oceans filled with enormous leviathans; nauseatingly putrid environments saturated with disease-causing fungi; and the endless, existential void of infinite space.

If that may be a better option, give to those Fire storms VFX the propper fire dmg, instead for a beat tick dmg.
