Hi,
Does anyone know where this drops?
“Black Grimoire of Og’Napesh”
http://grimdawn.wikia.com/wiki/Black_Grimoire_of_Og%27Napesh
It’s completely random, it can be dropped by anyone. I do have several copies of that epic, regular and empowered.
It’s a level 40 blue item so it can drop anywhere level 40 items drop. There’s no way to farm a specific blue item with very rare exceptions; Oggy is not an exception so just keep farming.
Veteran has more blue drops than normal; Elite has more blue drops than Veteran. Bosses have more blue drops than heroes; heroes have more blue drops than champions. If you have or can get decent quantities of dynamite, treasure troves are a good source of blues.
Or post into the trading threads and see if someone else has one for you.
Just random luck from a 40+mob!
It’s also craftable, but you can only craft it as a level 75 item after unlocking the blueprint.
