Zargash

The first time Zargash would drop to 0 hit points as a result of taking damage, he instead drops to 1 hit point.

Zargash wears a bat-shaped amulet that has the properties of a ring of feather falling.

Zargash casts one of the following spells, using Wisdom as the spellcasting ability (spell save DC 13):

At will: light, thaumaturgy

1/day each: command, gaseous form, hold person, silence, speak with dead

Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d8 + 2) bludgeoning damage, or 7 (1d10 + 2) bludgeoning damage when used with two hands.

Ranged Spell Attack: +5 to hit, range 60 ft., one creature. Hit: 25 (4d10 + 3) necrotic damage.

Zargash targets the lifeless corpse of one Humanoid he can see within 30 feet of him and commands it to rise, transforming it into a zombie under his control. The zombie takes its turn immediately after Zargash. Animating the zombie requires Zargash's concentration (as if concentrating on a spell). The zombie reverts to an inanimate corpse after 10 minutes, when it drops to 0 hit points, or when Zargash's concentration ends.
