Here's my character, Lorwyn Suaril, a Rogue / Warlock / Arcane Trickster. She's a thief who got into a bad situation years ago and has been trying to get out of her pact with her Patron ever since.

She's got the trapfinding thief skills and flies around shooting eldritch blasts while invisible during combat. One of her tricks is to use Eldritch Chain with Hammer Blast to sunder the weapons of 4 enemies at once.

The magic items are pretty standard. The custom Ring of Skeleton Keys is just an upgraded Lockpicking Ring, basically. The amulet combines the Greater Chasuble of Fell Power and Dragon's Eye Amulet. I added the Nimbleness special ability to the Celestial Armor and increased the enhancement bonus.
