So I found these; (source)
Book of Crow Form
Scroll of Touch of Death
Tome of Blink
Sigil of Necromancy
There are more of them but for now they seem to be only one per class.
We dont have that much info about these at the moment but that never stopped anyone from having a discussion!
Since we know these will only work in ashran on lvl 100 players i can imagine that the druid one is completely useless compared to the dk and mage one for instance.
How do you feel about these?
