The Lolth fallen aasimar has the same ability score increases as regular fallen aasimars

Drow-like but not an elf so no elvish. No celestial because no angelic ties.

You have disadvantage on attack rolls and on Wisdom (Perception) checks that rely on sight when you, the target of your attack, or whatever you are trying to perceive is in direct sunlight.  Didn't add all the modifiers because this is situational so remember this! And maybe find sunglasses

Cantrip for light is the same as usual, but gives off light similar to a blacklight instead of a regular light

Starting at 3rd level, you can use your action to unleash the divine energy within yourself, causing your eyes to turn into pools of darkness and 8 large, skeletal spider legs extend from your lower torso. As you fold your humanoid legs into a seated position, you can operate these legs for one minute. Your size stays the same, but you can now use spider crawl to skitter up walls and ceilings. Your crawling speed is still 30ft (a spider would probably crawl faster than this, but I want to avoid OP. Talk with your DM if you want a faster crawling speed).

The instant you transform, other creatures within 10 feet of you that can see you must each succeed on a Charisma saving throw (DC 8 + your proficiency bonus + your Charisma modifier) or become frightened of you until the end of your next turn.

Your transformation lasts for 1 minute or until you end it as a bonus action. During it, once on each of your turns, you can deal extra necrotic damage to one target when you deal damage to it with an attack or a spell. The extra necrotic damage equals your level.

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

You have resistance to necrotic damage and radiant damage.
