fudges:
Removed trap sense and uncanny dodge abilities from barbarian levels.
Increased in class skill list for barbarian levels.
Feat progression fudged slightly so Grar wouldn't have to wait two extra levels to get the second requires-rage-as-a-pre-req feat to get into frenzied berserker. This is just a matter of timing; he does have the minimum four levels of barbarian that would allow two feats if the first level had landed on a multiple of three.
Went up to EL22 to get the key fourth level frenzied berserker ability. Starting equipment reduced to EL 18 gold value in compensation.
Used strength bonus for intimidate checks.
