Beast had decided to help out Shadow and Blackie first. The battle between them and the demon was one where a single mistake could spell the end of the other party. He pulled back an arrow and patiently waited for an opportunity.
They had been fighting for some time now, just like the others, and had completely gotten used to the rhythm and tempo of the battle. Nobody had joined in the fight, which made the three completely lose track of their surroundings.
One well-placed arrow would be enough to flip the table on the demon and get him in trouble, just one arrow was enough.
As that was going on, Reign was fighting against the hammer-wielding demon. As the enemy now only had one hand, he was forced to only use the hammer while the shield was on the ground.
The demon was angry, Reign could see it in his eyes.
