The Web-weaver

At 1st level, you have struck a bargain with an otherworldly being of your choice: the Fiend, which is detailed at the end of the class description, or one from another source. Your choice grants you features at 1st level and again at 6th, 10th, and 14th level.

Silk Salvo

Your patron lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Fiend Expanded Spells

Spell Level	Spells
1st	Dissonant Whispers, Ray of Sickness
2nd	Acid Arrow, Web
3rd	Bestow Curse, Conjure Barrage
4th	Giant Insect, Greater Invisibility
5th	Insect Plague, Bigby's Hand (Appears as a Giant Spider)

 

 

Beginning at first level your patron imbues you with the power of a spider. As an action you can fire a burst of webbing at your enemies.

As an action, make a ranged spell attack against a target within 120 ft. On a hit, the target takes 1d8 force damage, and must succeed on a Strength save equal to your spell save DC or be restrained. As an action, the restrained creature can make a Strength check equal to your spell save DC, escaping from the webbing on a success. The effect also ends if the webbing is destroyed. The webbing has AC 14,  and 10 + twice your warlock level hit points, vulnerability to fire damage, and immunity to bludgeoning, poison, and psychic damage. You may have a number of creatures equal to your proficiency bonus webbed at one time.

This feature creates more than one blast when you reach higher levels: two at 5th level, three at 11th level, and four at 17th level. You can direct the beams at the same target or at different ones. Make a separate attack roll for each beam.

Additionally, any eldritch invocations that would affect Eldritch blast, also affect this feature.

 

Skittering Parry

Starting at 6th level, your link to your patron begins to transform you, giving you four spider-like appendages that grow from your sides. You gain the following bonuses. 

• You have a climbing speed equal to your walking speed. In addition, you can move up, down, and across vertical surfaces and upside down along ceilings, while leaving your hands free.
• When you are targeted by a melee attack roll, you can use your reaction to give yourself a +2 bonus to your armor class until the start of your next turn, if you successfully block an attack using this bonus, the bonus is lost until this reaction is used again.

Survival Instincts

Starting at 10th level, your connection with the spider realm enhances your own survival instincts granting you the following features. 

• You have resistance to poison damage, and immunity to the poisoned condition.
• Additionally your parry reaction's AC bonus increases by 2 to a +4 bonus. And the AC of your webbing increases from 12 to 16
• You can tap into the web of the roots, and natural fault-lines.  You gain Tremor sense with a 30 ft radius.  

Invasive Species

Starting at 14th level, you have an open connection with your patron that allows you to fill the webbing of your silk salvo with hundreds of your patrons young, causing many bites to the target.

When a creature fails your saving throw for your Silk Salvo feature, you can also inflict a paralysis condition on them for 1 minute. A target can make a constitution save at the end of each of it's turn to end the effect early. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a short or long rest.
