Grease (T1, W1)

Level4

You cover a solid surface with a layer of slippery grease. Any creature in the area when the spell is cast must succeed at a Reflex save or fall prone. A creature can walk within or through the area of grease at half normal speed with a successful DC 10 Acrobatics check. Failure means the creature can’t move that round and must then succeed at a Reflex save or fall prone, while failure by 5 or more means it falls prone (see the Acrobatics skill for details). A creature that doesn’t move on its turn doesn’t need to attempt this check and isn’t considered flat-footed. The spell can also be used to create a greasy coating on an item. Unattended material objects are always affected by this spell. If you attempt to affect an object in a creature’s possession, the creature can attempt a Reflex save to negate the effect. If the creature fails the initial saving throw, it immediately drops the item and must attempt a new save each round it attempts to pick up, hold, or use the item. A creature wearing greased armor or clothing gains a +5 circumstance bonus to Acrobatics checks to escape a grapple and a +2 circumstance bonus to its AC against grapple combat maneuvers.
