I really think Precious Gems of Discord could be stronger, given that it is a restock war prize, after all (even if it is a tad on the cheap side). Only 4 icons, without even any crystal slots? I've seen lower-rarity weapons that at least had 1 slot.

Would anyone like to make some suggestions on how it could be improved?

I've got one idea: make it so that weapon does something really cool if you have 7 of it equipped (I know there are some weapons that have altered properties if you have other certain weapons equipped, like some of the Red Rreign stuff). If PGoD already does have some property like this, my apologies (though I currently haven't seen that). Thoughts?
