Dunno what to say about Pain Reflection, it feels out of place, usually in RPGs it is an active skill, i.e. it is a tactically used skill.
I see a Pain reflection as a rare high level necro spell. But regular skill ? Like a regular soldier or a rat will get hit by arrow so archer might die, heart attack perhaps ? Pretty crazy world.
I believe that pain reflection skill is a kind of test or placeholder, because it might not work in the game.
