I'm very early on in the game right now. The amount of locked stuff is staggering. I can put up with locked chests, but I got into the dungeon near the starting town (a trapdoor on a hill with some goblins inside) and wham, a closed door halfway in, and no key on any of the goblins I slew.
Is lockpick skill a must to have in this game? How much am I missing here?
