Does your character level effect what can drop from treasure runs?

So you can trade by putting items into your trade stash and sharing the diablo\Data\player_save\shared.box file and have your friend replace his with yours. Made playing with a friend over skype pretty fun as we were trading some drops etc. There is dupe protection also

all points into dex. recommend vendor resetting for hp/res items.

recommend you get teleport asap. collect gear with magic on it and then pop a magic potion to learn the spell. you dont need to have the required magic that you needed to learn the spell to cast it
