there is also a speed run to kill temp boss fast to play with more items and get stuff early if you want debug commands early
Nah without doing commands if you go to the cardboard dungeon and save and reload your save till you get a fountain next to the save point inside the dungeon you can repeatly farm that fountain by using it to give a temp stat for 3 turns in this case size and then repeat till you get around 3k in size and have step ability and then run to temp boss area to kill the tunnel guard and the temp boss without commands
Also to make sure the fountain gives you size dumb the starter 20 points into size only
