Actions

Multiattack. The giant makes two Scythe or Soul Bolt attacks.

Scythe. Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit:21 (3d8 + 8) slashing damage plus 11 (2d10) necrotic damage.

Soul Bolt. Ranged Spell Attack: +8 to hit, range 120 ft., one creature. Hit:26 (4d10 + 4) necrotic damage. If the target has the frightened condition, the giant gains temporary hit points equal to the damage dealt.
