Belial does not take part in phase 1, opting instead to call in the troops. He'll summon a large amount of [[Veiled SentinelsSentinel]]s and [[Velied Evoker]]s to challenge the player. The sentinels just have a melee attack, the evokers have the magus ability to wiggle around a lot and summon a ring of electricity that damages anything inside of it. They both retain the snakeman ability to vanish and then re-appear.
