Yep. Tried it on my Berzerker, the damage increase was kinda insane with earth gems in the weapon.
Now I'm purely a magic using Warden (Was there a successful hybrid before?) and my M.Atk is around 2.3-4ish (44currently). As of now, my Earth Atk says 13.6% while my Water is at 5.6%.
I might just keep switching back and forth and see which one works better I suppose.. Thanks for the help anyways!
