Mana and Health Vials
When in a new dungeon, some enemies will drop Mana or Health vials when killed. You can leave them and return later to use them when needed. They will not disappear for some time, allowing you to save them and not waste them when you are already close to full health or mana. Your Mana, as well as special attacks, also will recharge over time. You can wait between waves of enemies for them to get restored.
Spirits
Always upgrade your Spirits and try to have them at maximum. Once there, Evolve them. If you use the same element type of Spirit for upgrading, you will get an experience point bonus.
Treasure
After selecting "Story Quest" you will have a choice of difficulty settings. Story Mode dungeons can only be played once. Always choose the highest difficulty in order to collect the best treasure. Selecting the easy difficulty will result in the worse treasure, and will not be helpful at end game. When in a dungeon, break every container that you can find for a chance of more treasure, better equipment, and Spirits.
