EXP wise, 2hit Petris and Ulu2 1hit which would be better exp? And if possible, a EXP/HR would be nice so i could decide if it's worth not being able to sell leech there. I'm trying to get higher level so I can 1 hit Petri faster.
Do you 1 hit any of the petris? Like 6/15 or so? Or is every kill 2 hits? If it's the latter, I'd stick with ulu2 I think. Also, most people are not going to want to buy 2 hit petri leech. And if you're just leeching your own mule, ulu2 would be better because of the drops. More money npcing and especially if you get a few decent Red craven.
Pretty sure petri is faster exp if you grind by yourself on fp mage or something. The mobs there just give a lot more exp each
