the ruststone weapons SUCK!
get the ancient stone weapons
they give stuff like island of the gods and epitaph blade.
both are VERY RARE!
i learned the best way to do it is to
1 keep getting rust/ancient stones
2 put them in your bank
3 when you get like 10 make them
4 say the third one is the weatherd great sword.
then every 3 stones would be a good weeapon
whichever stone is a good weapon the number then is the amountuntil the next stone is a good one.
EXAMPLE u have 7 stones
1=iron striker
2=golem blade
3=island of the gods (good)
4=fin blade
5=red wing
6=weathered dual blades (good)
7=dark lance
