暗黑破壞神2 how to get L93 Hedrodic Cube(合成方塊)

1. make a new character
2. don't pass all cube mission in normal, nightmare or hell (borrow cube from people help u )
3. don't pass all quest 5 in act3
4. u must not pass hell act3 ---> don't kill mephi
5. drop all cube on ground (no cube in inventory or stash) if u want to get L93 cube
6. go travincal and kill all counciller , after that L93 cube will drop depend on how many people are in party that has no cube with them.

P.S. As long as step 2, 3, 4 is remain no complete , the cube can get infinity !!

maybe there is some other way, but this is what i test and succeeded ^^
