Despite you can't do everything, and some items will be open only by leveling, i found this tool fun, and it makes pretty shields, like this :

and you can save it as .png file.

I look forward to checking it out. Thanks!

If you use the generator link you get to save your design to the account and I was given a $10 starter pack (something I wouldnt have bought :p )

Not played the game yet so will reserve judgement :D

Anyone know how it runs in WINE?
