Tentacle(触手, Shokushu?), also called Tentacles and Tentacl is a recurring enemy ability in the series. It is a physical attack that can either inflict statuses, deal heavy damage to a party member, or Drain HP from a party member.
Tentacle is an ability used by Orthros. In the first phase of the battle, it will deal two hits to random targets; in the second phase of the battle, the number of hits increases to four. Each hit counts as a physical attack and can be nullified by Blink.
Tentacle, known as Feeler in the demo release, is the special attack of Guard Hound and Unknown 2, as well as being the standard attack for Lost Number. It deals minor damage in Guard Hound's and Lost Number's case, but deals major non-elemental damage when used by Unknown 2. Tentacle Drain, used by Blood Taste, deals minor non-elemental damage and drains HP from the target.
Left Tentacle and Right Tentacle, both used only by Plant Brain, inflict minor non-elemental damage to one target. Tentacle, used by Plant Spider, also inflicts minor non-elemental damage to one target. The more dangerous Virus Tentacles, used by Malboro, inflict moderate non-elemental damage as well as Virus to one party member.
