Editing List of D&D Spells (section)

==Grease==
Conjures a great puddle of slippery, slimy oil on the ground; anything entering this puddle risks falling over, and is forced to move more slowly, which is great for crowd control or keeping a single bigger monster vulnerable and defenseless; [[ogre]]s and [[troll]]s in particular tend to have a bad time with this spell. In older editions, at least, the puddle is explicitly oil, so you can set it on fire and create an el-cheapo fireball effect.
