Psh...just farm the hammer. If you get lucky and get it 3+ times it's awesome. Also, invince yourself before equipping the hammer if you're stuck in a crowd. If you really need to heal yourself switch your hammer/mace back on, heal, and re-equip the ultimate hammer again. >:O
(Try to aim for those higher on the leader list because they give more points.)
This was actually a second-place finish from a while back. Of course the first place winner was a charmed fighter but meh...it was still decent. (...also note that I am not a godly combat cleric by any means...)
