Bane of Ooze!
+2 Ooze bane great club.
When Slime Smasher destroys and Ooze type monster, it creates a massive explosion of slime in every direction. All creatures in a 5 foot radius of the destroyed slime take 1d4 acid damage (Not including the wielder). On an attack roll of natural 20, if the targeted creature is an Ooze, that creature must save vs. death effects or be destroyed instantly.
