Gloves of Thievery. I don't recall where I got them (does anyone know?) but they give you Advantage on Sleight of Hand rolls. Give them to Astarion and you'll never lose a lockpick or disarming kit again. Well, almost never. There are some DC 30 traps and locks, but with the gloves even those become doable.
lol ironically a merchant sells these. The Zhent hideout guy I think.
