Frightening Injection Feat
You accompany your injections with a promise of terrible effects that shakes your target’s resolve.
Intimidate 3 ranks
When you successfully inject a creature with a substance (including a biohacker’s biohack) using a weapon that has the injection special property, you can attempt an Intimidate check to demoralize that creature as a move action before the end of your turn. A creature can be affected by this ability only once per day.
