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.

• Pyrrhic Focus – Calen burns his own health reserves to restore his mana. His focus also increases healing done to Calen by 500%.
• Mana Barrier – A powerful barrier envelops Sinestra, continually replenishing any lost health at the expense of her mana.

Pulsing Twilight Egg – Sinestra has stored vast reserves of twilight energy in these massive eggs.

• Twilight Carapace – The Pulsing Twilight Eggs are normally impervious to all damage. In moments of dire need, Sinestra directly siphons from the eggs and causes their Twilight Carapace to drop temporarily.

Twilight Spitecaller – These twilight dragonkin periodically stream into the room during the clash between Calen and Sinestra.

• Unleash Essence – The Twilight Spitecaller releases a torrent of twilight energy that afflicts all nearby enemies, inflicting damage equal to 10% of each target's maximum health every 1 sec. Conventional interrupts cannot prevent the casting of the spell, but other effects that cause loss of control may be effective.
• Indomitable – If a Twilight Spitecaller is incapacitated for more than a brief period of time, it regains control through a surge of sheer will. The Spitecaller becomes immune to all bonds and restraints until a player removes this effect, and inflicts 40000 Shadow damage and knocks back players within 8 yards.

Twilight Drake – Twilight Drakes swoop in from the sides of the cavern during the clash between Calen and Sinestra.

• Twilight Breath – The Drake's breath inflicts 57600 to 62400 Shadow damage in a 25 yard 60 degree cone in front of it.
• Absorb Essence – If a Twilight Drake comes into contact with a pool of Twilight Essence, it siphons that energy and causes the pool to shrink and eventually vanish entirely. Each charge of Essence absorbed increases the Drake's damage by 10%, and its health by 10%. This effect stacks.

Essence of the Red – Calen bestows a blessing of Alexstrasza upon the raid, granting all players 100% melee, ranged, and spell haste, and causing them to regain 5% of their maximum mana per second. Essence of the Red lasts for 3 min.

Wrack – Sinestra causes a random player to suffer Shadow damage every 2 sec. for 1 min. with the damage taken increasing rapidly.
