Pets Guide

To level up your pet, you have to take them to battle with you, hoping that they
will step on crystals for exp. You can leave them at the stables to graze,
which will also gain them exp and levels.
Leaving them to graze is more efficient. They will, for certain, gain exp.
Taking them to the battlefield to gain exp only 'works' if they actually get
exp crystals or not. When pets gain new levels, they gain new technique and
abilities too. It is best that you leave them alone to graze and bring them
out occasionally to let them 'see' the world. Pets have low HP and only leveling
them up can raise their HP. You may think that pets are lousy after you caught one.
Actually you are partially correct. The pets that you caught early in
the game is rather weak but the eggs that you will catch when you are
further into the game has higher HP and stats. They are cheap and easy
to manage compared to Golems. There is another way to let those cute
little things gain new level. The method is that you will equip the
forbidden ring from Daena in the early part of the game and bring your
pet out to battle. Your pet would gain the crystal level as your main
character gets them. If you have just started playing Legend of Mana,
here is a tip. DONT lose the forbidden ring. Do not ever use it to
make logic blocks or sell it. There is no gameshark code to get it back.
