The wounds were getting larger and it seemed like there was no end to the bleeding. Balarama felt something was very off so he decided to use his Celestial Magic to fix it.
The spell worked and most of the bleeding stopped but his regeneration was not acting as it intended to. More of those gunshots continued and this time, Avatar Balarama was a little more careful in his guarding. He parried most of the shots away with one that had managed to slip in because of the angle that it came from.
It was only at that point that the Celestial Warriors under Balarama's command decided to become the body shield for their lord and liege. They were killed instantly for those who had received a fatal wound. It seems like the worries of the other Avatars fighting at the other side of the battlefield were coming true for Balarama as well.
