Actually you can get all the neccessary items by playing triple triad- but you're better off doing this from the start or else your cards wont be too hot. Personal best is having a weapon like Punishment or Twin Lance by the end of disc 1 Still, you could always get the items by fighting but you'll probably need to be a high level. Hint: for easy energy crystals go to Esthar after the lunar cry. Inside the city will be a man standing in one of the roads. Speak to him and he'll laugh and turn into an Elnoyle (as you do) The easiest way to kill it is to use 100 deaths and status attack or zombie and revive. Try mugging it before it bites the dust!
