Rahovart

Description
As the lord of the underworld Rahovart's name alone strikes fear and terror into the hearts of even the most evil of beings.

This is a boss mob that is usually summoned via a Boss Event using a Rahovart Altar. This boss has 3 Battle Phases.

All Phases:
Rahovart will constantly bombard the area and all players with giant Hellfireballs. Any players that are too high up (flying) will be bombarded with a massive swarm of Nether Souls so stay low.

Phase 1 (100-60% Health)
Summons Belphs which explode over time then give Rahovart energy. At full energy casts a Hellfire Wave attack outwards. This attack will remove all buffs so be careful! The goal here is to keep the number of Belphs low so that Rahovart cannot unleash Hellfire Wave too often and when he does, run!

Phase 2 (60-20% Health)
Summons Behemoth minions which explode over time and give Rahovart energy. Summons Belph minions that no longer explode. At full energy casts Hell Wall which rotates 360 degrees. This attack will remove all buffs so be careful! Like phase one, in this phase you need to keep the number of Behemoth low to reduce the number of Hellfire Walls and when the walls are created, run around Rahovart in a full circle away from the wall. The Belphs don't matter but can be harmful in large numbers.

Phase 3 (20-0% Health)
Summons Belph, Behemoth and Nether Soul minions, none explode over time. Constantly gains energy. At full energy, creates a static Hellfire Barrier at a random angle. This attack will remove all buffs so be careful! Killing 2 summoned Belphs or Nethersouls or 1 Behemoth will lower a barrier. The goal here is to not let Rahovart create too many barriers as you may run out of combat space.

Trivia

 * Rahovart is a reference to the Cyberdemon from the Doom series. Both are bipedal, have a stereotypical demon-like appearance, and a large weapon replacing their left arm which shoots out projectiles.
 * The Hellfire Wave may reference attacks done by the Cyberdemon in Doom (2016).
 * The Hellfire Wall may reference how the Cyberdemon in Doom (2016) conjures walls from the ground to limit player mobility.
