Blaster(ブラスター, Burasutā?), also known as Blast, Bluster, or Recoil, is a recurring ability in the Final Fantasy series. It has various effects in different games, and has also appeared as Blue Magic. It is usually used by Coeurls and similar monsters, with some exceptions.
Blaster is an enemy ability that causes instant death to one or all targets. It has a hit rate of 70 but always hits a stopped target, and is vulnerable to Runic. It cost 20 MP for the enemy to use.
VIIIToramas, mostly found in and around Esthar after the Lunar Cry has occurred, can use Blaster. It can either Petrify or instantly kill a party member, and the monster will only use it while it is standing.
There are three variants of this skill. Coeurl's Blaster inflicts petrification to the target while Master Coeurl's Blaster inflicts instant death and ignores Deathproof completely, and finally, Coeurlregina's Hyper Blaster inflicts instant death, too ignores Deathproof completely.
X-2Coeurl's Blaster reduces the target's HP to exactly 1. Queen Coeurl's Death Blast has the same effect as Blaster, plus instant death. The Gun Mage can learn Blaster from either of these two abilities, however, the Blue Bullet version removes 90% of the target's maximum HP (as long as the target is not immune to Gravity) and costs 30 MP to cast.
