Bio Barrage

Bio Barrage (バイオバラージュ) is a Shotlock in Kingdom Hearts Birth by Sleep that can be used by Aqua, Terra, and Ventus. It can be unlocked for purchase in the Mirage Arena by reaching Level 15 and purchasing it for 2500 Medals or created through Command Meld, but there's only a slim chance of making it. It is one of the more powerful Shotlocks with a max lock of 8. Launch a salvo of projectiles that poison targets (50% chance). To trigger extra attacks, press at a well-timed matter to fire additional blobs (based on your timing rating).
