SFRPG Antagonize Feat
You know how to make foes extremely angry with you.
Diplomacy 5 ranks, Intimidate 5 ranks
As a standard action, you can antagonize a foe that can see and hear you by attempting a Diplomacy or Intimidate check (DC = 10 + your opponent’s total Sense Motive skill bonus, or 15 + 1-1/2 × the opponent’s CR, whichever is higher). If you succeed, the foe is off-target and takes a –2 penalty to all skill checks for 1 round plus 1 additional round for every 5 by which your result exceeds the DC, or until it makes an attack against you, forces you to attempt a saving throw, or damages you (whichever comes first). Once you have attempted to antagonize a foe, that foe is immune to this ability for 24 hours. This is a language-dependent ability.
