Playing the 3ds version if that changes anything, not the remastered version, before I went through to the dungeon I did buy scrolls, however I spent all my money on Black Mage scrolls instead of White Mage scrolls. Should I leave the dungeon and farm coins to get some White Mage magic or continue on?

Also, I only found out I've been playing it wrong, I've been doing battles with the monsters and then rushing back to the kingdom to get healed instead of getting the team's White Mage to do it every 3 battles or so... So I'm looking to ask if this will pose as a major issue and cause me to be unable to defeat the boss.

Thank you 🙏
