Encounter phases
Adventure Guide says
- Stage One: I Will Deal With You Myself! At the outset of the battle, Sinestra is weakened from past battles and from nurturing the Twilight brood.
- Stage Two: I Tire of This! When Sinestra is brought to 30% health, she draws upon ambient energy to restore her power and erects a shield to protect herself.
- A Clash of Flame and Twilight The red dragon Caelestrasz, Calen in his humanoid form, comes to the party's aid and engages in a magical duel with Sinestra. The duelist with the most mana gains the upper hand.
- Stage Three: Now Die! Once the players destroy the Pulsing Twilight Eggs, Sinestra brings her magical duel with Calen to an end and attacks the players with her full fury. Empowered by the twilight eggs from which she reclaims her siphoned energy, Sinestra no longer deals reduced damage.
- Heroic Difficulty Only Sinestra is only available in Heroic Difficulty.
