Sorcerous Origin: Bitten by a Magical Spider

Your innate magic comes from being bitten by a magical spider.  This spider may have been monstrous, or a spirit totem that manifested itself as a spider.  The spider’s magic was mingled with your blood or that of your ancestors.

Spider Sense

You gain proficiency and expertise in the Perception skill.  Your proficiency bonus is doubled for this skill.

Spider Blood and Spider Agility

As magic flows through your body, it causes physical traits of the spider to emerge.   At 1st level, your hit point maximum increases by 1 and increases by 1 again whenever you gain a level in this class.

Additionally, you have the agility of a human-sized spider.  When you aren’t wearing armor, your AC equals 13 + your Dexterity modifier.

Poisonous Affinity

Starting at 6th level, you gain resistance to poison damage.  Additionally, when you cast a spell that deals poison damage, you can add your Charisma modifier to one damage roll of that spell.

Spider's Step

Beginning at 14th level, you can climb walls like a spider.  You have a climbing speed equal to your walking speed.  You can move up, down, and across vertical surfaces and upside down along ceilings, while leaving your hands free.  Also, you can't be caught in webs of any sort and can move through webs as if they were difficult terrain.

Spider's Aspect

Beginning at 18th level, you can channel the innate fear creatures have of spiders, causing those around you to become frightened.  As an action, you can spend 5 sorcery points to draw on this power and exude an aura of fear to a distance of 60 feet. For 1 minute or until you lose your concentration (as if you were casting a concentration spell), each hostile creature that starts its turn in this aura must succeed on a Wisdom saving throw or be frightened until the aura ends. A creature that succeeds on this saving throw is immune to your aura for 24 hours.
