Improved Intimidating Ki (3.5e Invocation)

As Intimidating Ki except the penalty on an opponents attack rolls within 10 feet increases to -4, and as a free action on the Saiyan Warrior's turn, he can strengthen and focus the evershifting and flowing light around him in a display that others find disturbing. When he focuses his aura in this manner he may make an immediate intimidate check to demoralize all opponents within 30 feet that can see him and have no more than 2 hit dice more than he does. While the Saiyan Warrior's ki flame is about his body he gain a +2 circumstance bonus on all intimidate checks. The Saiyan Warrior does not gain this bonus against characters that have levels in Saiyan Warrior, or any class that counts for the purposes of Ki Detection unless the Saiyan Warrior has 3 or more hit dice than the target.
