Blast Burn is an offensive Fire-type move. It can be taught by the Special Move Tutor in Tsukinami Village, at a cost of 4 Blue Shards. In 1.03, it could be taught by the Ultimate Move Tutor in Tsukinami Village for four shards of each color, and in versions prior to that, it could be taught by a tutor in Venesi City for free. The Venesi Tutor was restored in 1.2.
Blast Burn inflicts damage and then forces the user to recharge during the next turn. Unless this attack misses, the user will always have to recharge.
