Step 1: Make some foundries. Get the
Moonstar Agent title.
Step 2: Roll a new toon. Equip your Icosahedron Ioun Stone.
Step 3: Buy level 60 epic ring & epic enchant and put in stone (continue adding more as slots unlock).
Step 4: Enjoy blowing things up and generally speaking being invincible, as
here.
At level 4, my GF does more dmg than my GWF at lvl 30. Plus every hit regens lots of health so you couldn't die if you tried. Enjoy!
