Duergar Kavalrachni

When the duergar hits a target with a melee attack while mounted on a female steeder, the steeder can make one melee attack against the same target as a reaction.

The duergar has advantage on saving throws against poison, spells, and illusions, as well as to resist being Charmed or Paralyzed.

While in sunlight, the duergar has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.

The duergar makes two war pick attacks.

Melee Weapon Attack +4 to hit, reach 5 ft., one target. 6 (1d8 + 2) Piercing damage plus 5 (2d4) Poison damage.

Ranged Weapon Attack +2 to hit, range 100/400 ft., one target. 5 (1d10) Piercing damage.

The duergar magically turns Invisible for up to 1 hour or until it attacks, it casts a spell, or its Concentration is broken (as if Concentrating on a spell). Any equipment the duergar wears or carries is Invisible with it. While the Invisible duergar is mounted on a female steeder, the steeder is Invisible as well. The invisibility ends early on the steeder immediately after it attacks.
