When encountered, the Ruloi attack with offensive and defensive plasma-based spells while flying about. If they take damage, they will flee to one of their regeneration chambers and return when healed. There are 40 Ruloi in total in the Citadel who must be destroyed in order to free Dawn and the other imprisoned women.
The Ruloi will utilize the following spells:
- Plasma Bolt - a non-tracking ranged bolt of plasma energy
- Plasma Spray - Shoots a 6-foot long ring of Plasma Bolts
- Plasma Wall - summons a set of columns that cause significant damage when Luther walks into them
- Plasma Form - a slow moving mass of plasma that attaches itself to Luther and adsorbs health.
