Sinisters have a powerful bite, but their more potent abilities are magical in nature.
Hold Monster (Sp): Sinisters can cast hold monster once per day. They usually save this ability for escaping from creatures more powerful than they are, but may use it when hunting if they are ravenous.
Missile Deflection (Su): Sinisters are surrounded by a 5-foot radius field of force that helps deflect melee attacks (represented a +4 deflection bonus to AC). In addition, this field stops missile attacks, turning away normal missiles and absorbing spells such Melf's acid arrow and magic missile.
