My main problem at the moment (I'm preparing for the final fights) is the composition of my party and ... locks. I want Shadowheart (Thunder Cleric) and Gale (Evocation Wizard) in the group, for some synergies and upgrades, an I-Win-backup and two minions. I also actually want Jaheira (Eldritch Knight in my game) because I would like to have some hard hitting melee/thrower in the party. My main is a crit build Warlock/Sorceress/Fighter with little except damage and pleasure in her mind.

So none of us can lockpick well. Our boni at most are about +7 buffed, no comparison to Astarion's +14 unbuffed. That is quite annoying. Knock is no alternative as it eats spell slots. Astarion is a really strong ranged Fighter/Rogue, but I would prefer Jaheira. Often I really miss Astarion, sometimes I even have to get him from the camp which feels not very immersive and is clumsy.

How do you deal with locks without Astarion or a Rogue/Bard in the group? Do you rely on items, like the glove for advantage? Do you burn thief tools?
