I think I’ve run into a bug with the Army Flame attack. Seems that the damage reduces when there are less arks in the opposing team. Was doing around 700 damage to a Metallodious in the Inifinte Dungeon in a party of 3, then damage dropped to the 300 range when it was solo.
Will try to get some screens in another battle. Just wanted to see if other people were experiencing this.
EDIT: Damage with 3 allies:
Damage vs solo ark:
