[RPG] How Does the Grease Spell Interact with Fire


Can you light the spell grease on fire? If so, what are the effects of doing so? (How long does it burn, does it do damage to creatures standing in it / coated with it, etc.)

Best Answer

No, Grease (as per the spell), is not flammable.

There is already a spell that does this:

Incendiary Slime
(Complete Mage, p. 108)
Level: Sorcerer 2, Wizard 2,
A slick, greasy liquid seeps from the targeted object, thoroughly coating it. This spell functions like grease (PHB 237), but the liquid is also highly flammable. If any fire damage is dealt within the area of the spell (or to the subject of the spell), the spell's area (or subject) bursts into flame. This effect deals 4d6 points of damage to anyone in the area (or holding the subject), but also ends the spell's duration. A successful Reflex save halves this damage. (emphasis mine)

They would not have created a level two spell that specifically calls out being flammable as the distinction if the level one spell were already flammable.
