Bheur Hag (Improved) (Fey)

Graystaff Magic. The Bheur Hag carries a Graystaff, a magic staff. The Bheur Hag can use her flying speed only while astride the staff. If the staff is lost or destroyed, the Bheur Hag must craft another, which takes a year and a day. Only a Bheur Hag can use a Graystaff.

While holding a Graystaff, the Bheur Hag can cast the following spells using Charisma as her Spell Save DC (spell save DC 15, +7 to hit with spell attacks).:
At Will: Hold Person, Ice Knife (at 3rd level)
3/day: Cone Of Cold, Ice Storm, Wall Of Ice

Ice Walk. The Bheur Hag can move across and climb icy surfaces without needing to make an ability check. In addition, the Bheur Hag ignores difficult terrain made of ice and snow.

Innate Spellcasting. The Bheur Hag’s innate spellcasting ability is Charisma (spell save DC 15, +7 to hit with spell attacks). She can innately cast the following spells, requiring no material components:
At Will: Detect Magic, Frostbite, Gust, Ray Of Frost
3/day: Armor Of Agathys (at 3rd level), Cause Fear, Fog Cloud
2/day: Fear, Mirror Image
1/day: Control Weather

Multiattack. The Bheur Hag can make two attacks.

Claws. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 9 (2d6+3) slashing damage plus 16 (4d8) cold damage.

Maddening Feast. The Bheur Hag feasts on the corpse of one enemy within 5 feet of her that died within the past minute. Each creature of the Bheur Hag’s choice that is within 60 feet of her and able to see her must make a DC 15 Wisdom saving throw. On a failure, a creature is Frightened of the Bheur Hag for 1 minute. On a success, a creature is immune to the Bheur Hag's Maddening Feast for the next 24 hours.

While Frightened in this way, a creature is Incapacitated, can’t understand what others say, can’t read, and speaks only in gibberish.

A creature can repeat the saving throw at the end of each of its turns, ending the effect on a success.

Snow Camouflauge. While in snowy terrain, the Bheur Hag can take the Hide action. When she does so, the Bheur Hag makes any Dexterity (Stealth) ability check at advantage.

Frigid Rebuke. When the Bheur Hag takes damage from a creature the Bheur Hag can see within 60 feet of her, the Bheur Hag can force that creature to make a DC 15 Constitution saving throw. On a failure, a creature takes 10 (2d10) cold damage.
