Her weapon's barely but not quite sentient, which means going into a dunj is probably immensely stupid since she by definition can't know it well enough to get powerful magic, but this dunj has been a pest for a while and no adventurers care about little backwaters getting their crops ruined by monsters. She just needs to get in, close the portal, and then she's out, no diversions for treasure, and that really doesn't sound too hard.
She manages to get a few rooms in even with her barely-not-normal sword, cutting down the weird bird ladies with a twist in her gut - she knows they respawn and aren't intelligent, but ugh, tell that to her instincts.
She finds a little aesthetic perch thing that could be a bench after clearing the room, and sits down to take a deep breath and a few sips of water, and maybe clean her sword while she's at it. She's heard that helps things.
