Incendiary Slime

2-level Conjuration

Slick flammable slime covers the ground in a 10-foot square centered on a point within range and turns it into difficult terrain for the duration. When the slime appears, each creature standing in its area must succeed on a Dexterity saving throw or fall prone. A creature that enters the area or ends its turn there must also succeed on a Dexterity saving throw or fall prone. In addition, if any fire damage is dealt within the area of the spell (or to a creature which failed its saving throw to avoid falling prone), the slime bursts into flame. Any affected creature or creature in the area must make a Dexterity saving throw, taking 4d6 fire damage on a failed save or half as much damage on a successful one. Setting the slime alight ends the spell’s duration.
