I like the bow a lot cause of the stun effect it has, I juuusst got the hammer and havent tried it yet. I did make a crazy ass awesome gem for 10,000.
Even with the Gem Field expanded it still takes up so much room I lost my Slot Fury and Shockwave sword swipe, but the gem boost my def so much and im the mage type. I think the gem field will get extended one more time, that should help.
