Pain is status ailment which appears only in Final Fantasy XIII trilogy. It disables the target's usage of physical abilities, where the related Blind ailment merely impairs them. It is classified as a "debilitation" status.
The player can cast the status to enemies with the Saboteur spells Pain and Painga learned fairly late in the Crystarium. The player can resist against the status with the following accessories: Pain Dampener, Pain Deflector, Ribbon, and Super Ribbon.
Pain reappears in Final Fantasy XIII-2, but can only be inflicted by enemies and some Saboteur monster allies.
