With the mana accelerator skill, it is very easy to level up the casting medals very quickly.

I just got Iron Knight on my warrior, by walling a Marauder into the corner and casting berserk on him 10x in a row in two successive battles. Use one inquisitor to pump rage for conversion to mana.

Also split Maurauders can be used to cleanup 4 corpses per battle. You can get away with this at least on the first island on impossible.

And of course the already mentioned two treasure chests per battle with treasure searcher.

I also left some of the incredibly easy battles on the first island (e.g. devil fish) for when I could return with walls or a disabling spell so I could grind medals for 10 turns.

I try to makes sure all my mana and rage is spent by battle end.

Also use the pet regularly for him to level. Question though. I can't figure it out. Pet exp gained seems to be linked to number or difficulty of skills used. But then it seems to be capped, such that the dragon gains only a certain percent of the total battle exp. Does anyone know the formula? How many times must I use the dragon each battle to max out exp for the battle?
