Remove disease has this clause:
"
The spell also kills parasites, including green slime and others."
If slimes are oozes and oozes are slimes, that means we're cookin'. Now, load up on green paint.
If you can get both of these to work, your Cleric can insta-kill oozes that fail their Fort save!
But wait! Wouldn't it be more convenient to do this at range? Of course! Get your local Artificer to make lots of
remove disease potions. Put these potions and the paint in a backpack attached to a hose.
Start singing.
This trick is usually impractical and dubiously legal, but probably hilarious if it works.
