The skill is supposed to be usable on Sera itself, on her master, and enemies. Currently, it only works on enemies.
I attempted to change it on skill_db.txt:
8021,1,6,[color=#ff0000]1[/color],0,0x1,0,5,1,no,0,0,0,none,0, MH_PAIN_KILLER,Pain Killer
I tried changing it to 5(enemy+self), 17(friend+enemy), and 21(enemy, self, enemy). All of those attempts ended with the skill not being usable(click the skill, the target select pointer didn't show up).
I myself have seen Genetics using it on themselves on iRO. The iROwiki article also claims it can be used on anyone.
