I thought that these new weapons would completely make certain relics/mythics/empyreans worthless. I just recently got the katana from skirmish and found that this is not the case. To get some of those perfect augments that people have shown possible (like the 170 base damage, 12 strength and 10% weaponskill damage on the greatsword) is pure freaking luck.

First you actually need to get the base weapon to drop which isn't too bad but then welcome back to synergy based luck on augments. Unless you feel like spending millions on high tier parts, you won't get anything too good. My group spent 2.2m each for T2 Head, Body and Feet for one run. I was the only one who got a +1 stone and +2 ones are rare as hell unless you do the high tier parts.

Sure it's possible to buy the stones with currency from skirmish, but it takes around 9.8k of the obsidian fragments for a +2 ghastly stone. I got around 300 fragments from the one run. You do the math. If you think getting perfect augments on an Armada Hauberk or Valkyrie Body is costly, have fun with these weapons.

Just as an example of possible augments. For a +1 stone on my Katana I got +14 damage and 3 dexterity.
