1. get Moss levels to 5/5/5/5 and equipment that boosts Moss talents (Eye of the Forest, Evermoss Robe, amulets, extra talent point) so that moss lasts for 11 or more turns
2. get mental crit rate to 100%
3. get Mucus to at least 4/4/5/0
Then place on autocast at all times: Mucus and the four Moss talents.
The mucus produces mucus oozes and because moss always crits at 100%, and because crit adds two turns to mucus oozes, and because the moss talents are instant cast, the mucuses stay around until killed by an enemy.
Then, if you are really wanting op, get blighted summoning to give mucus oozes virulent disease talent.
And pump CUN and get heroism infusion.
So my current character has CUN at 152 and the infusion takes it to 178, giving 17 oozes. I also have Oozing Heart, which gives 3 extra oozes.
Thus I can be running 20 oozes at a time, though I rarely get to this!
Here is a a typical shot:
