Bellandra, Witch of Blight

Blighted Vitality. When Bellandra deals necrotic damage, she gains temporary hit points equal to half the necrotic damage dealt (Max 10 temporary hit points).

Corrupted Bloom. Plants within 15 ft. of Bellandra become difficult terrain for her enemies.

Saint's Remnant (1/Encounter). The first time Bellandra is reduced to 45 hit points or fewer, she immediately activates her Blight Domain. 

Blight Domain. The battlefield becomes difficult terrain except within 10 ft. of Bellandra. Bellandra may only take Legendary actions when her domain is active.

Multiattack. Bellandra makes two Thorn Slash attacks.

Thorn Slash. Melee Spell Attack: +6 to hit, reach 15 ft., 1 target. Hit: 10 (2d6 + 3) piercing damage plus 4 (1d8) necrotic damage. The target must succeed a DC 14 Strength saving throw or have its speed reduced to 0 until the start of Bellandra's next turn as thorny vines wrap around its legs.

Blight Bloom (Recharge 5-6). Corrupted flowers erupt in a 20 ft. Sphere centered on a point Bellandra can see within 60 ft. Creatures in the area make a DC 14 CON saving throw taking 18 (4d8) necrotic damage and the creature is Poisoned until the end of its next turn or half damage only on a success.

Withering Embrace (1/Day). Bellandra targets one creature within 30 ft. The target makes a DC 14 WIS saving throw. On a failure, the creature takes 22 (4d10) necrotic damage and Bellandra regains the same number of hit points. On a success, the creature takes half damage and Bellandra gains no hit points.

Entangling Growth. Choose a point within 30 ft. A 10 ft. square becomes overgrown until the start of Bellandra's next turn. The area is difficult terrain.

Petal Shield. When Bellandra is hit by an attack, reduce the damage by 8. The attacker takes 4 piercing damage from magical thorns.

Legendary Action Uses: 2 in Blight Domain. Immediately after another creature's turn, Bellandra can take a legendary action, choosing from the options below. She can only take one legendary action at a time and only at the end of another creature's turn once her Blight Domain is active. She regains all expended legendary actions at the start of her turn.

Thorn Grasp. Bellandra causes roots to erupt beneath one creature she can see within 60 ft. Creature must make a DC 14 Strength saving throw or have its speed reduced to 0 until the end of its next turn.

Blighted Blossom. A corrupted flower blooms beneath a creature Bellandra can see. The target must either, move at least 10 ft. before the end of its next turn, or take 8 (2d8) necrotic damage.

Bloom of Sorrow (Costs 2 Actions). Bellandra sheds a shower of corrupted petals. Each creature within 10 ft. of Bellandra must succeed on a DC 14 Constitution saving throw or take 4 (1d8) necrotic damage, and Bellandra regains hit points equal to the damage dealt to one creature.
