Greater Zombie (5e Creature)
From D&D Wiki
Medium undead, chaotic evil
Brute A melee weapon deals one extra die of its damage when the zombie hits with it (included in the attack).
Undead Fortitude. If damage reduces the zombie to 0 hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, the zombie drops to 1 hit point instead.
Longsword. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 11 (2d8 + 2) slashing damage, or 13 (2d10 + 2) slashing damage when used in two hands.
Parry. The zombie adds 2 to its AC against one melee attack that would hit it. To do so, the zombie must see the attacker and be wielding a melee weapon.
