Seiken Densetsu: Heroes of Mana
This game is titled Heroes Of Mana in North America, Europe, and Australia, and Seiken Densetsu: Heroes of Mana in Japan.
Use the following trick to pass through a level easily.
Usually you will start of with one of Gaia's Stone and a couple
of Treant's Berries. Summon Gatherers to collect lots of Gaia's
Stones and Treant's Berries. You can then construct a building
to summon more powerful monsters of your choice to help kill your
enemies. Note: Do not do this on the "Tears Frozen In A Chant"
chapter because it will take too long and Baxilios will storm
