On most spells (burning hands, web etc) it only affects enemies, not friendlies.
Grease, however, affects friendlies -- but only when cast by a toon.
If a mob casts grease, it doesnt (seem to) affect (their buddies, aka baddies)... Why is that?
It seems to me, being a magic spell, grease should NOT affect friendlies; it should be the dex equiv of web.
But if it does affect friendlies (which would make it unique among most spells, which don't affect friendlies), then, when the baddies cast it, it should affect baddies too
