The Blood Weavers are a clandestine sect of Lolth's devoted followers, trained in the art of infiltration, sabotage, and assassination. Masters of the blade, they meld deadly precision with dark magic, serving their Mistress with unwavering loyalty. Operating from the shadows, they strike swiftly and efficiently, spreading fear and chaos in their wake to further Lolth's power. Each member harnesses their ki to enhance their dark abilities, making them formidable adversaries to any who dare oppose the will of the spider goddess. Through their actions, they seek to advance the dark agenda of Lolth and ensure her dominion over the realms.

Silk Veil

Starting when you choose this tradition at 3rd level, you can use your ki to duplicate the effects of certain spells. As an action, you can spend 2 ki points to cast darkness, invisibility, pass without trace, or spider climb, without providing material components. Additionally, you gain the minor illusion cantrip if you don’t already know it.

You gain proficiency in martial weapons. 

Spider's Bite

At 6th level, your training enables you to pull threads of knowledge from your foes, much like a spider lures its prey. When you hit a creature with a Flurry of Blows, you mark them as cursed, their blood crying out to reveal their secrets. If a cursed creature misses you, you can swiftly retaliate with an unarmed strike, sinking your metaphorical fangs into their vulnerability.

Moreover, you gain insight into your foe's weaknesses, tasting their blood to discern their vulnerabilities. You can learn two of the following attributes about the target: Damage Vulnerabilities, Resistances, Immunities, or Condition Immunities, akin to a spider tasting the essence of its prey.

In addition, you begin to weave your own webs, gaining advantage on initiative rolls, striking before your foes can react. You gain advantage on all initiative rolls.

Blood of the Queen

By11th level, your connection to the Spider Queen deepens, honed through blood rituals akin to a spider's ancient rites. You gain expertise in Stealth, moving as silently as a spider prowling its web. When you vanish from sight, you leave no trace, your movements as elusive as a spider's steps on silk.

Furthermore, your senses sharpen, guided by the pulse of ancient blood. Once per turn, if you've reacted, you can spend 1 ki point to seize another reaction. Like a spider sensing prey's slightest movement, you react with swift precision, ensuring no threat escapes your awareness

Venomous Strike

At 17th level, you gain the ability to force the your spider's venom into someone’s body. When you hit a creature with an unarmed strike, you can spend 3 ki points to inject venom into your target. The target must succeed on a Constitution saving throw against your Ki Save DC (The saving throw DC for the spell equals 8 + your Wisdom modifier + your proficiency bonus.). If it succeeds, it takes 5d10 poison damage. If it fails, the creature takes 10d10 poison damage and receives the poisoned condition for 1d10 hours.
