Shadowspawn

You have sworn yourself to the Shadow and pledged your soul to its service. As more and more of your soul is sacrificed to its dark purpose you are blessed with the Boons bestowed upon its spawn. As you grow more powerful your soul slips away, until you are one of the Fades, a Myrddraal, a cursed creature, powerful, but cursed. 

Cafar Swarm

When you choose this archetype at 3rd level, you gain the ability to unless an infestation of shadowspawn called Cafar, or "Blood Wasps" that will beset your enemies. 

Once per long rest, as an action you can unleash a Cafar Swarm. For one minute as a bonus action on your turn they may preform one of the following actions:

• Swarm of Blood
  • One target within 30 ft of you must succeed on a Constitution Saving Throw or be beset by the swarm. On a failed save the target takes 1d8 poison damage plus your intelligence modifier This increases to 1d10 at 11th level and 1d12 at at 17th level. (The swarm is considered an extension of you, but can not benefit from sneak attack)
• Swarm of Pain
  • One target within 30ft of you must succeed on a Wisdom Saving Throw or be beset by the painful stings of the Swarm. On a failed you have advantage on any ability checks used for gaining information (e.g. Intimidation or Persuasion) 

• Swarm of the Shadow
  • The Swarm can be used to darken any light source size class Small or less. The swarm can only darken one light source at a time. If this effect is used to attempt to blind a creature they must fail an Intelligence Saving Throw or be blinded for the duration of the effect. The effect last until the start of your next turn unless a bonus action is used to maintain the swarm. The target may choose to use an action to make an attack against the swarm (AC 18) attack against the swarm (HP 15). Once the swarm is dispersed all its effects end until the next long rest. Once the creature has successfully evaded this effect it can not be effected by it again until after a long rest.

If your "Passive Stealth" is greater than a creatures Passive Perception you are hidden from their sight without needing to make a Stealth check.
