The only way to obtain most of these new and powerful weapons are through crafting. But they are harder than normal recipies for several reasons. To start, they all require Loremaster treasure cards. The only way to obtain these rare treasure cards is through farming Loremaster herself or through crafting them also. These prove to be a challenging ingrediant.
Shadow Forged Weapons
With the release of Khrysalis part 2 came new Shadow Forged Weapons. These powerful weapons can cast spells all on their own, like how pets can get talents to cast various spells on their own.
The next ingrediant is Stardust, which can be a rare drop from Comet Tail, or you can transmute 15 Comet Tail to make one Stardust. Each wand also needs certain treasure cards based on the wand's school, such as the Heart of Darkness requires Skeletal Pirate treasure cards, all of these can be bought in the bazaar.
