Whats a good amount of Jump/Dexterity for a melee build?

[CitizenKing]

To cover jumping for exploration. Started as a Thief but I've been pumping my points equally into Strength, Defense, and Speed. I'm getting good results in combat, but I'm definitely hitting a point where I'd like to be able to reach places I normally can't. How much Jump should I be aiming for?

There are spells to assist with exploration, so you don't actually need DEX if you don't want to dump the points into it. That said, the 30's should suffice for most jumps.
