Pyroclasm (メルトクリムゾン, Meruto Kurimuzon?, lit. "Melt Crimson") is a recurring ability in the Final Fantasy series. It is Vaan's trademark Limit Break, first appearing as his Level 3 Quickening in Final Fantasy XII.
Pyroclasm is Vaan's Level 3 Quickening. As with all Level 3 Quickenings, it deals damage equal to a random number between 1 and 230, multiplied by Vaan's Strength, and costs three Mist Charges to execute.
Pyroclasm is Vaan's Quickening, acquired by defeating Belias. It deals heavy damage to all enemies over the targeted area.
Pyroclasm is the third command entered during Vaan's EX Burst. It deals ten hits of Bravery damage with a power of 3 per hit, and does physical damage.
Pyroclasm is an ability exclusive to Vaan, learned at Level 40. During BMS, each time a boss-type enemy enters, Pyroclasm damages that enemy based on Vaan's Strength, Magic and Level.
One of Vaan's cards can use the Pyroclasm ability. The player chooses 1 Forward, and deals it 2000 damage for each Backup they control. Pyroclasm requires two Wind CP and Dulling Vaan to use.
