at this point, you need to decide if you want to just fight monsters and get loot, or get the 6 Perks that make it easier to get more loot.
if your are fighting monsters and getting loot, the choices are to climb floors or farm for loot. climbing focus's on surviving and dealing lots of damage, farming focus's on getting lots of loot from defeating monsters and stuff, while surviving.
if you are going for Perks, you need to get 200% experience bonus, and then some survival and damage ability, because you only need to survive around floor 100-110. experience from monsters stops increasing at floor 100. any space left over can have some farming affixes, like gold find and luck.
also, do a search on beginner and noob tips, there has been a lot of advice given to help players new to DQ.
