You can check this thread if you want to discuss any gem changes you’d like to see.

Although I’m always in favour of buffing anything I think that’s a little overkill and it would make these gems a must in all builds leaving all other in the dust…

PS.

20.000.000.000% ?? I haven’t seen such numbers even on modded console items…
