A rogue archetype whose strength is in setting traps. I know the traps in BG2 are quite out of control but that doesn't mean trap mechanics can't be balanced better. There's a joy in crafting your own traps, selecting the right trap for the right enemies, setting them up in advance, and waiting for enemies to step on them. I don't even know if such an archetype exists in PnP, and even if such an archetype will be implemented I wouldn't expect that you get to craft your own traps, but I'm still secretly holding out hope. Just getting to set traps would be fun enough.
