Dark Mother's Curse

Your deal with the dark powers has given you an unfortunate side effect, as Lolth has redesigned your physiology in an image they much prefer, you gain 4 additional spindly limbs 2 under each arm. Resembling spider legs, these limbs do not have hands at the end but finish into a point. 

At 1st level you have learned to use these new limbs for doing simple tasks and bolstering your close range attacks. You have a pool of d4s that you spend to access these bonuses. The number of dice in the pool equals 1 + your warlock level.

You can roll a d4 from the pool and add it to a strength check

On a succesful melee attack you can roll a d4 from the pool and add this to your damage as piercing damage, this can only be activated once per hit.

Your pool regains all expended dice when you finish a long rest.

Arachnid Movement

Starting at 6th level, you have learned to use your new appendages to your advantage, using them to put yourself in a better vantage point. You can use 3 dice from your pool of d4 (from Dark Mother's Curse) to cast the spell spider climb with the following variations; targeting only yourself, duration is reduced to 10 minutes, no concentration is needed to maintain the spell.

Spider Queen's Image

Starting at 10th level, you have been gifted the ideal physiology by your devious patron. you gain a resistance to poison damage and advantage against saving throws against the poison condition.

you are also less susceptible to the charm effects of creatures. granting you advantage on saves against being charmed, if you already have advantage against being charmed you are instead immune to the charmed condition.

Demonweb Form

You have gained the ability to transform into  shape more reminiscent of the wicked patron you serve.

Starting at 14th level, as an action you can transform your physical form in to that of the cursed form of a Drider for 10 minutes. 

While you are transformed, the following rules apply:

• Your game statistics are replaced by the statistics of the Drider, but 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. If the Drider has the same proficiency as you and the bonus in its stat block is higher than yours, use the Drider’s bonus instead of yours. 
• When you transform, you assume the Drider's hit points and Hit Dice. 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. As long as the excess damage doesn’t reduce your normal form to 0 hit points, you aren’t knocked unconscious.
• You can cast spells as normal.
• You retain the benefit of any features from your class, race, or other source and can use them if the new form is physically capable of doing so. However, you can’t use any of your special senses, such as darkvision, unless your new form also has that sense.
• You keep your equipment on you in your new form, weapons you have can be used for the Drider's multiattack action.

Once you use this feature, you must finish a long rest before you can use it again.
