Black Hand Zealot

Fanatical Devotion. The zealot has advantage on saving throws against being charmed or frightened. When reduced to 0 hit points, it can make a DC 10 Constitution saving throw. On a success, it drops to 1 hit point instead (once per long rest).

Obsidian Blade. The zealot’s weapons are jagged and black, dealing an extra 3 (1d6) necrotic damage on a hit.

Zealous Frenzy (Recharge 5–6). When the zealot drops an enemy to 0 hit points, it can immediately make one melee attack as a bonus action.

Multiattack. The zealot makes two melee attacks.

Obsidian Shortsword. Melee Weapon Attack: +4 to hit, reach 5 ft., one target.
Hit: 6 (1d8 + 2) slashing damage plus 3 (1d6) necrotic damage.

Throwing Dagger. Ranged Weapon Attack: +4 to hit, range 20/60 ft., one target.
Hit: 4 (1d6 + 2) piercing damage.

Dark Chant (1/Day). The zealot utters a blasphemous phrase in the tongue of the Hand. Each ally cultist within 30 ft. gains advantage on their next attack roll before the end of their next turn.
