Arachnid Form

Starting at 1st level, your patron bestows upon you the ability to transform into a horrifying visage of their most favoured form. As an action, you can transform into a Giant Wolf Spider, with the following changes:

• You gain a bonus to your AC equal to your Charisma modifier.
• When you use your bite attack, you can use your Charisma modifier, instead of Strength or Dexterity, for the attack and damage rolls.
• You may use your spell save DC for the poison effect and web ability.
• You retain your alignment, personality, and Intelligence, Wisdom, and Charisma scores. You also retain all of your skill and saving throw proficiencies, in addition to gaining those of the creature.
• The hit point maximum for your form is increased by an amount equal to your warlock level + your Charisma modifier.
• When you revert to your normal form, you return to the number of hit points you had before you transformed. However, if you revert as a result of dropping to 0 hit points, any excess damage carries over to your normal form. 
• You can’t cast spells, and your ability to speak or take any action that requires hands is limited to the capabilities of your beast form. Transforming doesn’t break your concentration on a spell you’ve already cast, however, or prevent you from taking actions that are part of a spell, such as witch bolt, that you’ve already cast.
• You choose whether your equipment falls to the ground in your space, merges into your new form, or is worn by it. Worn equipment functions as normal, but the DM decides whether it is practical for the new form to wear a piece of equipment, based on the creature’s shape and size. Your equipment doesn’t change size or shape to match the new form, and any equipment that the new form can’t wear must either fall to the ground or merge with it. Equipment that merges with the form has no effect until you leave the form.

You can stay in this form for 1 hour or until you choose to end it early as a bonus action. At 7th level, you may use this feature to transform into a Giant Spider. At 14th level, you may use this feature to transform into a Giant Scorpion.

Once you have used this ability you can't use it again until you finish a short or long rest.

Enveloping Darkness

Starting at 6th level, you can use the all consuming darkness of your patron in response to harm. When you take damage, you can use your reaction to cast darkness centered on yourself - without expending a spell slot or material components. 

Once you use this feature, you can't use it again until you finish a short or long rest.

Fear Incarnate

Beginning at 10th level, your patron teaches you how to turn the fear inducing effects of your enemies against them. You are immune to being frightened, and when another creature attempts to frighten you, you can use your reaction to attempt to show them the true meaning of fear, the ultimate darkness that it your patron. The creature must succeed on a Wisdom saving throw against your warlock spell save DC or be frightened by you for 1 minute. At the end of each of its turns, the target can make another Wisdom saving throw. On a success, the effect ends on the target.

Arachnid's Blessing

Starting at 14th level, you can temporarily alter the mind and physicality of your enemies. As an action, choose up to 3 creatures that you can see within 60 feet of you. They must make a Wisdom saving throw against your warlock spell save DC. On a failed save, they are transformed into a Giant Spider, for 1 minute or until your concentration is broken (as if you are concentrating on a spell). This effect ends early if the creature takes enough damage to reduce it to its original form. The transformed creatures are not hostile to you and will attack the nearest creature to them. Roll initiative for the summoned creatures as a group, which has its own turns.
