Karrnathi Undead Soldier

The soldier has advantage on an attack roll against a creature if at least one of the soldier's allies is within 5 feet of the creature and the ally isn't incapacitated.

If damage reduces the soldier 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 soldier drops to 1 hit point instead.

The soldier attacks three times with one of its weapons.

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

Ranged Weapon Attack: +4 to hit, range 150/600 ft., one target. Hit: 6 (1d8 + 2) piercing damage.

The soldier adds 3 to its AC against one melee attack that would hit it. To do so, the soldier must see the attacker and be wielding a melee weapon.
