Crown of Ereshkigal (Awakened)

(Requires Attunement)
Once per day, you may use your reaction to turn
a critical hit against you into a normal hit. Once
per day, you may unleash an unearthly howl
dealing 4d6 Necrotic damage to all creatures in a
30ft radius. If a creature that is alive is reduced to
0 HP, the ability to reduce a critical hit is
immediately recharged.
Curse: While attuned you will not willingly
remove this crown and never willingly
hide this crown.
