Ink(スミ, Sumi?), also known as Ink Jet, is a recurring enemy ability in the series that naturally inflicts Blind on a party member, and is usually one of the signature attacks of aquatic enemies such as the Kraken and Ultros. It usually inflicts minor non-elemental damage as well.
VIIInk is an item the party can use to inflict Darkness on one enemy. It can be stolen from Bad Rap. This is the only way for the player to inflict the Darkness status on the enemy, although this serves little purpose: Darkness halves the physical accuracy of weapon-based attacks, but due to a bug, the status only affects the commands Attack, Morph, Deathblow, Mug, Slash-All, Flash, 2x Cut, and 4x Cut.
Because enemies do not use the above commands they are unaffected by it, making inflicting opponents with the status pointless. The only real purpose of the item is to naturally observe the Isogin Smog ability used by Acrophies, who will only use the ability when the entire player party has the Darkness status.
Ink is a status inflicting ability that has 15 uses, it also increases a Robot's HP by 9. It inflicts Blnd to one group of enemies. This ability can be used by Ammonite, Kraken, Octopus, and Squid.
