Special Equipment. Warduke wears a dread helm (see appendix A) and wields a flame tongue longsword.
Multiattack. Warduke makes three Flame Tongue or Dagger attacks.
Flame Tongue. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit:7 (1d8 + 3) slashing damage, or 8 (1d10 + 3) slashing damage when used with two hands, plus 7 (2d6) fire damage if the weapon is aflame.
Dagger. Melee or Ranged Weapon Attack: +6 to hit, reach 5 ft. or range 20/60 ft., one target. Hit:5 (1d4 + 3) piercing damage.
Flaming Blade. Warduke ignites or extinguishes his flame tongue longsword. While aflame, it sheds bright light in a 40-foot radius and dim light for an additional 40 feet.
Second Wind (Recharges after a Short or Long Rest). Warduke regains 13 hit points.
Warduke's services as a remorseless killer-for-hire can be easily bought. The evil swordsman serves Kelek as a cohort and adventuring companion from time to time. He isn't terribly bright, which is why he leaves the plotting and scheming to others.
