Next to fall was the first boss in Tempest Keep (2nd one we killed though ofc!), the Phoenix God - Al'Ar which we 1 shot on the night after coming close several times the previous night including a couple of classic moments where he meteored the OT who was standing near a wall and respawned on the upper level leading to a wipe!  Doh!

Loot was:

[Phoenix-Wing Cloak] - Batou

[Band of Al'ar] - Brandii
