sorry i havent posted back sooner, thanks for all the tips again. anyways i played through act 2 up to where i was stuck and crafted some items along the way and when i got back to kulle i had around 1400 dps, think my life was was around 5000 but i dont remember, and had no issue with him or belial. right now im working on just finishing the nooks and cranny thing but not a single pack is a problem. so it seems dps is pretty important stuff, looks like i need to keep up with my gear if i plan to get anywhere.
Crafting is pretty good for weapons at this level. It's not too hard to get a socketed blue weapon with extra damage and then you add a ruby to it. The most important thing for weapons at this level is added min/max damage.
