try to buy best potion gun and just go in dungeon choose the sack with the hemlock potions and then suicide, go back and get more sacks keep doin this untill you have a full inventory, kill some mobs to get xp and upgrade all stamina skills to almost max, then run through all the rooms ignoring the mobs and going for the doors, get to risen knight and keep splashing him (btw forgot to say and to lazy to write it back there: you need a good melee as secondary to finish him if you don't have any potions left) at the end he will die and you will get his good armor (i rlly mean it it's sum gud sh).
