Traits

Unless Zalthar is incapacitated, it and undead creatures of its choice within 60 feet of it have advantage on saving throws against features that turn undead.
Actions
Zalthar makes three longsword attacks.
Melee Weapon Attack: +13 to hit, reach 5 ft., one target. Hit: 11 (1d8 + 7) slashing damage, or 12 (1d10 + 7) slashing damage if used with two hands, plus 18 (4d8) necrotic damage.
Zalthar hurls a magical ball of fire that explodes at a point it can see within 120 feet of it. Each creature in a 20-foot-radius sphere centered on that point must make a DC 18 Dexterity saving throw. The sphere spreads around corners. A creature takes 35 (10d6) fire damage and 35 (10d6) necrotic damage on a failed save, or half as much damage on a successful one.
