1st Level Spell
Magic Type: Conjuration
Ignisarian Classification: Grey Magic

Slick grease 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 spell is cast, roll any die. On an even number the grease spontaneously catches fire. On any odd number it does not, but casting a fire spell on it or another fire effect allows it to catch fire.

When the grease 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.

The grease is flammable. Any 5-foot cube of grease exposed to fire burns away in 1 round, dealing 2d4 fire damage to any creature that starts its turn in the fire.
