Shadow of the Colossus-esque build

[Daftendirekt]

So, I've always thought it would be cool to build a character similar to Wander from Shadow of the Colossus, and I think I've got a decent idea how. The ingredients I have so far are as follows. I'd appreciate any more tips or ideas to throw in:

-Hammer and Piton feat from Dungeonscape (possibly morph it to also allow Picks rather than a bludgeoning weapon + a piton)
-Whisper Gnome so that I can take:
-Underfoot Combat, Titan Fighting, Confound the Big Folk
-Leviathan Hunter PrC from Stormwrack

You are going to need some kind of regeneration or fast healing ability to match his ability to recover health on the fly.

Don't forget lots of skill ranks in climb.

Are you going to try to give him magical items? Not sure what equivalent in D&D there might be to his sword. A quiver with unlimited arrows might be an idea.

I'd consider given him levels in the assassin PrC. The death attack ability and sneak attack damage would match up with Wander's striking critical areas.

I don't mean I want to build Wander to a T. I just want to build someone who can take on a creature much larger than him and climb all over it while killing it.
