The white stones dont upgrade they only prevent breaking and can also down grade if your unlucky (happened with my tmq 6jacket from +9 to +6 TT_TT)
When you upgrade there 3 slots 1 for gear the other white stone and u stone

ok, but what the +2 ~+6 on that stone stands for?

the meaning is, white stone will work if u wanna upgrade again from +6 or +4 (armor). this stone is same like 2 stones in KR (before big update and they add to exchange this stones with +8 (blue) and +10 (green))



- blue : for surpass +3 to +6

- green : for supass +6 to +15

if u got broken, ur item still save. and ur item will be degraded -1 or -3.

arg, it can downgrade it, that sucks then. Those white stones arent that good as i thought they'd be

I still don't get it. they have a weapon lvl req?

.No the white stones are u60 so for gear under lvl 60

lol i hope white stones comes at tw version too i broke alots of legendary sutff ><

the big robot (40), giant alien (45)

the point for upgrade is "learn the card pattern" always choose " left or center " and timing for upgrade. so far i was got "success" without white stone. my tmq 7 armor (9, 10, 8), maybe i got luck, but not sure.
