What's your favorite Phantasy Star Exploit?
Submit the title of the game along with the system it appears on (I'm quite sure that is relevant info too) and then a detailed explanation of the exploit. You may add a title to your exploit if you like. I'll start out with one I think proves just how much of an asshole I really am.
Phantasy Star III: Generations of Doom (Nintendo Gameboy Advance)
Revenge of Old Yeller!
In this exploit, you simply allow a character with the healing line of spells (Res, Gires, Rever, & Anti) to die with enough TP to cast Rever. Simply select Techniques from the character screen menu and have the dead toon cast Rever on themself. Ding! One fully revived toon. Excellent if you lose your only healer (Miun).
Honestly now, how big of a jackass do you have to be to think that would work? Imagine my surprise to find it does work...
