Bit late but I really like opportunistic thief from humblewood, it goes very well with a thief rogue
“You have learned the tricks of the trade of thievery, allowing you to exploit opportunities for pick-pocketing both in and out of combat. You gain the following benefits:
Increase your Dexterity score by 1.
When a creature fails a melee attack roll against you in combat, you can make a Dexterity (Sleight of Hand) check against a DC equal to 10 + the target’s Dexterity modifier. On a success, you may steal any one item that is not being held or worn by the target.
Whenever you successfully use your Sleight of Hand skill outside of combat to steal an object, you may immediately conceal it flawlessly on your person, or put another object you possess in its place.
