Summoner Cheats

When trying to sneak in to the palace the first time as Flece, when you
go up the first flight of stairs, go right not left.  If you've
gone the right way, you will come into the room with the palace chefs. 
If you talk to the head chef, he will give you servant clothes. 
Put them on, and you can walk around with them and the guards won't
care.

A good strategy to get the jump on enemies is to first send Flece out in Solo Mode. Make sure she has the Sneak ability on so that she is invisible to most foes. Walk up SLOWLY to the rear of your target, then go into your action menu and use Backstab for a considerable amount of damage. This will bring Flece out of invisiblity mode, so after her initial attack bring her out of Solo Mode so that the rest of your team can swarm in and help out.

Try to have an encounter with some bacites. Kill all the bacites in site(or all of them at all.) Go to a yellow line(or exit line). Say no when it asks if you want to go to the worldmap. Turn around and start walking strait. Soon bacites should turn up. If you keep doing this you can get at least 20,000 to 100,000 gold pieces!!!
