The Dawn Matron is a fey boss. At the lowest Threat it has 1020 health, hits for 20 and carries 0 armor; the uber version you meet in the Mortal Arena has ×3 the health and ×1.75 the damage. You need Matron's Broken Halo to call it out.

It waits at the end of Dawnspire Sanctum, in place of Imp Overlord, and belongs to Demon Gate.

Every kill rolls its list twice. 8 Uniques sit on it: four ordinary ones splitting 90.0% of it between them, and four Exceptional ones splitting the last 10.0%, which puts any one of those at about 1 in 40 of what it gives up. The Exceptional ones are Doxology, Matins, The Evensong and The Noonday Crown.

It fights with Sweeping Ray, Censer Choir, Brand Of Dawn and Zenith, and changes phase at 55% health.

It calls in Choir Blossom.
