Final Fantasy V Advance Tips

Two islands West of Cresent are monsters called Prototypes. These are very hard and hardly take any damage. However, they are weak against Thunder, use your strongest attacks (Thundera and Ramuh). If you can maage to defeat it, it will give you a nice amount of EXP and ABP for this point in the game. You won't recieve any Gil, but its still worth it.

Note - you can steal Dark Matter from it, and it may drop a Ether.
