What is an ideal dex amount
for an axe barb? I'm thinking about
making one next climb.

Help please.

It's still about 120 dex, and rest strength. Although many people will do all strength barbs going axes, because the strength will add damage or ee somewhat. But having dex also means that you will get crits more often and will get crited against more less, so it's a win - win situation, thus why I go for 120 + Dex on my barbs

100 or 120

100 = higher crits less often
120 = lower damage crits more often
(at least for me )
