Multiattack

The malphas makes two Longsword attacks or three Shadow Bolt attacks. If both Longsword attacks hit one creature, the target must succeed on a DC 15 Constitution saving throw or be blinded until the end of its next turn, as shadows fill its eyes. A creature that can see through magical darkness has advantage on this saving throw.

Longsword

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage, or 9 (1d10 + 4) slashing damage if used with two hands, plus 10 (3d6) necrotic damage.

Shadow Bolt

Ranged Spell Attack: +7 to hit, range 60 ft., one target. Hit: 14 (3d6 + 4) necrotic damage.
