Dark Crystal Patron

[Pictogram]

Hey everyone! As the title states, i need ideas in brewing up a Dark Crystal Patron for 5e. I'm going to be running an evil game for some friends here soon, and 1 player is going to be playing a skeksis warlock and wants to have the Dark Crystal as their patron. Anyone have any ideas?

An ability to fission off an evil-er version of yourself.

A way to suck out life force butbuse it for more than just healing.

A summon for a spider crab construct

More to come.

I think a hypnotic, life-draining stare would be fitting. Something like the Archfey has, but not, you know... bad.

I also think an ability that causes nearby beasts and other low-intelligence creatures to go berserk from Darkening would be cool.

Spells probably include False Life, Vampiric Touch, Death Ward, and Crown of Madness.
