Barachiel is the second boss of the game and is fought on Lemuris. It is encountered when a Dragon Newt's body is transformed into a powerful monster by the Grigori.His hp is roughly 80,000-160,000(on galaxy mode).I can verify this as with the stragey I used at level 26 party aerage it took between 80-160 hits each dealing 1,000 damage on average due to stats buffing.
