You have trained to fight by imitating the hunting style of various spiders. You focus on controlling the movement of your enemy and whittling their health away with poisonous attacks. 

Poisoned Blood

Starting when you choose this tradition at 3rd level, you gain resistance to poison damage and the poisoned condition. If you already have resistance to one of these, your resistance becomes immunity. 

Venom Strikes

 Immediately after you take the Attack action on your turn, you can spend 1 ki point to turn your [Tooltip Not Found] damage type into poison. If at least one of these blows hits, the enemy must make a Constitution saving throw or become poisoned. 

Spider Web Fighter

 

At 6th level you gain the ability to spend 2ki points to cast Spider Climb on yourself. While this spell is active and you are on a wall or ceiling, you no longer have disadvantage on ranged attacks against enemies that are prone.

Spider Web.  (Action) Use 2ki points to create a 20ft square of webbing on the ground. On the first turn in which a creature starts or enters the web they must make a Dexterity saving through. Their speed is reduced to 0 on a failed save, or treat the web as difficult terrain on a successful one. 

Spider Bite

At 11th level, you can channel the poison in your blood into your attacks. 

All of your attacks do an additional 1d6 poison damage. 

Web Warrior

When a creature enters within 10ft of you they must make a Dexterity saving throw. On a failed save, you can use your reaction to move into melee distance and make one unarmed attack. 

Black Widow

When you hit a creature with an unarmed strike, you can spend 3 ki points to severely poison the enemy. At the start of your next turn, an afflicted creature must make a Constitution saving throw. On a failed save, the creature takes 10d10 poison damage and then another 10d10 at the end of it's turn. If it succeeds, then it take 10d10 poison damage.
