I have a theory about the Levels of Magic Crystals in Rune Factory Frontier, but I need confirmation from other players.
It appears that the three Monsters who drop them all drop the SAME Level of item: the Ignis, the Glace and the Soul.
At the start of the game, they dropped Level 1 Magic Crystals. Later, I was a little surprised to find that they ALL had begun to drop Level 3 Magic Crystals.
The description of a Magic Crystal, however, is:
Magic Crystal: A crystal made from magic. Time is needed to make it big.
'Time is needed to make it big.' Perhaps the Level increases according to the amount of time your character has lived in Trampoli, translated to the number of years you have played the game...
I would love to hear from players with higher levels of Magic Crystals and the year in which they were able to obtain these.
Another little puzzle to be solved: the level of the Items received from a Boss Monster in RFF. I, and other players, have received a Level 10 Giant Cockscomb and a Level 4 Giant Cockscomb on various occasions from the Giant Clucky. What determines the level of the 'special' item such as the Giant Cockscomb, the Red Core and so on?
