Alright this is sort of a fun trick, sure it's pointless, but fun. 1st off you'll need dark iron ale mug.
Start off by summoning the disgusting oozeling.
Next go to BEM stand at a crystal at Og'rila. i dont think it matters which one there's like 1000 of them just pick one. throw it at the top of the crystal, and he will go get it
he will start repeatadly drinking the mug and it wont go away for a while
may work at other places, i wouldn't know, i guess i'll encourage people to test it (even though it's pointless) just something i found while messing around and really bored
meh couldn't get the screenshot in...oh well sorry
