The Spider Matron

In the shadowy realms where the threads of magic weave through the very fabric of reality, there exists a pact forged in the depths of arachnid-infested domains. Warlocks who dare to embrace the essence of spiders discover a macabre and enthralling connection to the arachnid world. These wielders of dark and mystical webs entwine themselves with the eerie power of spiders, channeling the venomous touch, the silent agility, and the web-spinning mastery of their eight-legged allies.

Any equipment you're wearing or carrying melds into your new form, letting you retain its benefits.

You can stay in this state until your HP reaches 0 or you end the transformation as a bonus action. If you reach 0 HP this way, you are knocked unconscious when you come into your original form.
