Special Abilities

Cavatina (Su) Once per day as a move action, an oma can sing a telepathic song that either encourages its friends or dispirits its foes. The oma can grant a +2 morale bonus to ability checks, attack rolls, and skill checks to all allies within 60 feet. Alternatively, the oma can cause all enemies within 60 feet who fail DC 24 Will saving throws to take a –2 penalty to ability checks, attack rolls, and skill checks. This bonus or penalty lasts for 8 rounds.

Electrical Discharge (Ex) An oma can strike foes with a blast of electrical energy that has a range increment of 120 feet. When an oma scores a critical hit with its electric discharge, the target must succeed at a DC 24 Reflex save or technological items held by the target are unusable and do not provide any benefit to their wielder for 1 minute.
