Alkali Flasks are great against oozes and other acid-based creatures (double damage).
Bladeguard to protect your weapon.
And a bow with both blunt and normal arrows. Dealing damage from a better range with cheap arrows is the best way where possible. Oozes are slow but if you stand 20' away they can charge you.
Is this a home game?
1) 2 draft horses and a wagon, wheelbarrow. Generally oozes aren't small. You're gonna haveta camp out and you'll need the room, water, and supplies that you brought with a wagon. Don't forget some horse feed. Get a book on Oozes, Molds, Slimes an Puddins. It'll help pass the time.
Now that you're cozy...
2) Lots of chickens. Oozes aren't that smart and they'll chase anything down. Chickens are cheap and give them something to chase. Chickens don't fly and run pretty good so they'll give the oozes a good run for the money. Goblins and lost pets work but you'll get an atonement eventually which will eat up your profit, so just don't do it. Meanwhile use sling staves and such to pummel the oozes with alkali or acid from as far away as you can. Spells work too. When the oozes split then there'll be more to chase the chickens. Don't laugh too much while you're killin them dumb oozes.
Underground this could be an issue as you'll lose a lot of chickens flushing out the oozes. It's best to let the ooze run by and then get it.
3) Magic helps but is pretty costly. A wand of Locate Object (slime trails or a special adamantine coin) is probably you're best bet. It's cheaper to detect their trails then waiting to find them around a corner or steppin on one. Magic is silly sometimes. Detecting gold or treasure works good too as oddly monsters will always be around it. Go figure. Just keep away from your own hoard as the magic is lazy and overly specific sometimes. So why the adamantine coin? Well, they are hard to dissolve and chickens will eat just about anything... then when the ooze eats them you can track the coin in the ooze. You might want some wooden nickels and dicing bones too for oozes that can eat metal.
4) Good spells: Wand of Monster Summoning 1. Cheap pony that can get eaten instead of you and wants to attack the ooze...(unlike a Mount).
A scroll of Rope Trick 2@3 is handy or Meld into Stone 3@5 might help especially if you get caught and the ooze can't travel through stone. They can climb a rope but may be too dumb to figure you're in an extradimensional space.
If you have a Monk; Deliquescent Gloves $8000 and cover him in Grease so he doesn't get grappled.
