Is there a way to make Liquid Death work in a dispenser? will that be added in future? so far all it's done for me is spit the bucket of liquid death back out as an item. Conversely I've also tried placing an empty bucket in the dispenser and then trying to get it to pick up the liquid death to see if it would work that way, but no dice.
I can't promise this will work (because it's the one TC item I still haven't used), but maybe the arcane spa will do what you want. Or just a piston floodgate? I dunno.
