Reverse Lampion

So is it a good idea to stock up on Diamonds (should it be ores or refined?) and which other crystals, in GMS?

Btw, does anybody know the names for the Timeless weapons? Cause i thought the claw was called Timeless Claw...

There's 2 type of level 120 claw, Reverse Lamipon and Timeless Lampion.
The reverse can be forged by using 45 piece of time while timeless require 3 Time stone [Only from PB].
Timeless weapon is slightly stronger than reverse.
