Fire Emblem: Fuuin no Tsurugi Cheats

To give Fa unlimited uses, there is a glitch to exploit. To do you you need a thief. Now that you have a thief, you must be in Chapter 22 or 23. Put your theif next to a Mamakute, and then let an enemy confuse (berzerk) the theif. Next turn the theif will steal a Fire Stone from the Mamakute, which normal couldn't be done. You can then give it to Fa. The Fire Stone has unlimited uses so Fa will have unlimited uses.
