Shadowheart, Gale, and Karlach. My custom character is an Oath of the Ancients Paladin. I’m currently about halfway through through Act 2.
I don’t bother swapping, even for lockpicking and disarming. I instead respecced Gale to have 16 Dexterity and Sleight of Hand proficiency. I haven’t yet encountered any check that he couldn’t pass, especially with Guidance.
I’m kind of bummed about not taking Lae’zel to the creche, but I can always do that in another playthrough.
