Haha, three hours? I spent about 20+. Finally gave up and I was fighting pete the invincible and what do you know? He dropped one.
That was only for today I've got 4 lvl 50 characters and have tried with all of them hoping one of them would pull better luck, after a couple of weeks I think imma give it up, and I was wanting one to fight Pete with I always find myself running out of ammo in that fight --- GT Dark Soul x9
