Anobaith, Blade of Gwyneria

Fanatic Advantage. Once per turn, if Anobaith makes a weapon attack with advantage on the attack roll and hits, the target takes an extra 10 (3d6) slashing damage.

Cruelty Knows No Bounds. Anobaith has advantage on attack rolls against all creatures that are frightened, or have less than half their remaining hitpoints. Anobiath has disadvantage against any target that is not frightened or has more than half their remaining hitpoints, provided that she can see a target that is frightened or has less than half their remaining hitpoints.

Fey Ancestry. Anobaith has advantage on saving throws against being charmed, and magic can't put her to sleep.

Mask of the Wild. Anobaith can attempt to hide even when she is only lightly obscured by foliage, heavy rain, falling snow, mist, or other natural phenomena.

Multiattack. Anobaith attacks twice with her shortsword, or once with her Orb of Dragon's Breath and once with her shortsword.

Shortsword. Melee Weapon Attack:  +7 to hit, reach 5 ft., one target. Hit: 7 (1d6+4) piercing damage plus 10 (3d6) cold damage.

Orb of Dragon’s Breath (3/Day). Ranged Spell Attack: +7 to hit, range 90 ft., one target. Hit: 27 (6d8) cold damage.

All Shall Crumble. If Anobaith has attacked twice this turn, she can attempt to cause fear in all creatures within 30 feet of her. All creatures must make a DC 14 Wisdom saving throw or become frightened until the end of Anobaith's next turn. If Anobaith scored a critical hit on a creature during her turn before using this ability, that creature has disadvantage on the Wisdom saving throw.

All Shall Fall. If a creature has been reduced to 0 hit points on Anobaith's turn, she may cause all creatures within 30 feet of her to become frightened.
