Undead Barbarians?

[Belteshazzar]

Okay I am a Neanderthal. A Gestalt Barbarian/ Dread Necromancer. I am going for a kind of primitive caster vibe, yet I am wondering if there is a way for me to retain my rage once I reach 20th level and become a litch. I recall a feat somewhere that lets undead rage using Cha but can't find it now. Any suggestions for my character? Even if it's not directly applicable.

The general thing is for Con based stuff to switch to charisma usually. Although i hav no idea if it is written down anywhere with regards to barbarian rage.

[Nerd-o-rama]

No, that requires specific features or the "Unholy Toughness" feat, which I think only applies to hit points.

I believe you get 3 rages/day rounds/rage (whoops) and that's it, once you lose your Con score.

[Arbitrarity]

No, just however many rages from barbarian, and 3 rounds/rage.

Extend Rage (CWar) may help a LOT.

They're still pretty scary. Last undead barbarian I had ran all day long and raged without ever having to worry about fatigue.

He was a pain.

...and no fatigue. It's a wonderful life, Charlie Brown.

Oh, and a paralyzing Berserker Barrage of fists.
