How can sell/buy items in bulk? like selling 10-20 items at once or vice versa. Same question for when feeding the slime pet. Its time wasting to do it one by one
you can't. one by one it is, but you don't really need to sell anything. I played the entire game and only sold about 4-5 accessories throughout bc I'd already had them. I still ended the game at lvl 34 with over 30000 gold on a pure virgin playthrough.
