Okie!
Here is what I have so far, the theme is a Barbarian of 20th level, built in such a fashion to maximize his potential to dart behind the line, and break the enemy spell caster.
In a 4d6 drop lowest generation I did fairly well, the dice gods were kind. (base stated first)
Str: 18(-2Human) (+2Level)
Dex 16 (+2Level)
Con 12
Int 14
Wis 12
Cha 16 (+1Level)
His Traits are:
Skeptic (+2 to Illusion Spells)
Linebreaker (Belzken) (+10 Ft to landspeed when charging)
His feats are as follows so far:
Power Attack (H)
Combat Reflexes (1)
Cleave (3)
Combat Expertise(5)
Dodge(7)
Mobility(9)
Imp. Overrun(11)
Charge Through(13)
Wind Stance(15)
Greater Overrun(17)
Lightning Stance(19)
His Barbarian Rage Powers are as Follows
Superstition(2)
Witch Hunter(4)
Boasting Taunt(6)
Disruptive(8)
Eater of Magic(10)
Spell Sunder(12)
Renewed Vigor(14)
Powerful Blow(16)
Crippling Blow(18)
No Escape(20)
Thus far what I had thought to outfit this guy with was an Earth Breaker, Light armor, and a cloak of CHA for the Boasting Taunt ability, during his rage.
I was also considering Godless Healing in the build somewhere but couldn't figure where to work it in.
I would appreciate feedback, and help with this as the concept has me smiling and I would really like to play him at some point...
You need step up and following step. They can no longer 5' step away.
Look for AM BARBARIAN -- he'll show you the way.
Also, I recommend a one level dip into inquisitor for the spellbreaker archetype (roll twice on saves against mind-affecting effects) with the spellkiller inquisition (you get Disruptive for free, normally that's a level 6 fighter only feat). You can also potentially stagger spellcasters.
Oh, and some orisons to help you figure out where the spellcasters are (detect magic), and you can grab litany of sloth (no AoOs or casting defensively for a round, no save) and litany of weakness (fatigued for a round, no save).
