| Mirror Images | When Isiset's remaining health reaches 66%, she splits into three separate creatures. Each of the creatures represents one of her three main abilities. Killing one of the three images prevents her from using that image's ability for the rest of the encounter, but the other two abilities are empowered. When Isiset's remaining health reaches 33%, she again splits but into two separate creatures. These two creatures cast and correspond to her two remaining abilities. Killing one of these two images prevents her from using that image's ability for the rest of the encounter, but the sole remaining ability is further empowered. | |
| Astral Rain | The amount of Arcane damage dealt changes based on how many Mirror Images were previously destroyed by the players. | |
| Celestial Call | Isiset summons a number of Celestial Familiars to aid her. The number of Celestial Familiars summoned changes based on how many Mirror Images were previously destroyed by the players. No Mirror Images destroyed: One Celestial Familiar One Mirror Image destroyed: Two Celestial Familiars Two Mirror Images destroyed: Three Celestial Familiars | |
| Arcane Barrage | ||
| Veil of Sky | Isiset drapes herself in a protective shield that absorbs damage by draining Isiset's mana instead of her health and reflecting back a percentage of the spells cast at her. The amount of damage absorbed and the chance of a spell being reflected changes based on how many Mirror Images were previously destroyed by the players. |
