Good thing I decided not to main my fury warrior
Since fury warrior dual 2x 2handed weapon and assuming you have to Lego axe
It will cost you A total of 3800 flight stone and 60 Wyrm’s Awakened Crest and 90 Aspect’s Awakened Crest for the Lego axe
To upgrade a 2 handed weapon assuming you use Antique Bronze Bullion for the weapon you will need 3900 flight stone 45 Drake’s Awakened Crest 60 Wyrm’s Awakened Crest and 60 Aspect’s Awakened Crest
Better hope you get a hero or mythic track for you weapons but still the cost to upgrade Lego axe is crazy.
