While you are raging, you designate a single foe within 30feet of you that you can attempt to demoralize as a free action (see the intimidate skill page 76 of the Player's Handbook).
A foe that you successfully demoralize remains shaken for as long as you continue to rage.
Specifics: When you rage, it demoralizes your opponents.
When starting a rage the closest enemy must make a Will Save DC (10 1/2 character level Charisma modifier) or become shaken for the duration of your rage. A shaken character receives a -2 morale penalty on attack rolls, saves, and checks.
The scores after racial changes for Half-Orcs were: 20 Strength, 15 Dexterity, 15 Constitution, 10 Intelligence, 9 Wisdom and 8 Charisma.
But in all seriousness, the half-orc gets -2 cha, -2 int.If you fail the check by 5 or more, the target provides you with incorrect or useless information, or otherwise frustrates your efforts.You can also use Intimidate to weaken an opponent’s resolve in combat.This build draws heavily from the Rage and Frenzy abilities from all of the classes used.I am assuming here that Half-Orcs and Orcs are automatically proficient with the Orc Double Axe (and therefore have the Exotic Weapon Proficiency (Orc Double Axe) feat from creation).
