In addition to the above, both bosses have abilities that they cast when they reach a certain life percentage.

* Rathma simply summons void knights, these knights vary in element and number.  

** At 70% health: 1 Cold, 2 Fire, 1 Poison, at 50% HP: 1 Cold, 1 Fire, 2 Poison, 1 Physical, and at 30% HP: 2 Cold, 2 Fire, 1 Poison, 1 Physical. While the knights are out Rathma continues casting his other abilities and is invulnerable to damage until they are all killed. When fighting Mendeln and Rathma together in the third main phase, both bosses are invulnerable while the knights are out.  

* Mendeln has two different phase events.

** Blood golems: Mendeln teleports to the middle of the arena, and summons four blood golems. These march towards him, healing him if they reach him before dying. This occurs three times during the fight.

** Vine: Mendeln teleports to the middle of the arena, and starts casting poison vines, releasing a poison cloud around the edge of the arena. At the end of this sequence he casts a deadly poison nova with exceedingly long poison duration. This occurs three times during the fight.

** In addition to the above, there are four cold spires that cast a glacial spike that deals immense cold damage.

** These phases alternate starting with blood golems. During these phases Mendeln is invulnerable to damage until the golems have disappeared or the poison nova has been cast. When fighting Mendeln and Rathma together in the third main phase, Mendeln does not summon the blood golems.
