Also, try to get the four easier stones before you level up. Then right before you level up, battle for one of the hard stones (preferably whichever one is the easier to get). Hopefully you win; if you do, then level up and battle for the last sealstone since your AS will be full again after leveling up. Hopefully, luck will be on your side. If the last sealstone is particularly tough, you might need a crewmate.
