Oswin the Dread Warden

Hi all is it a EA bug that the skill book never seems to drop for the boss. I have completed the entire Interlude and have done this Boss prob a dozen times all new instances but the book never drops and while the boss marker on the map has the little X over the skull the reward still says "grants two skill points". Can anyone help with this? cheers o7

Same here: I killed the boss twice, but no reward. Oh well. maybe I'll have better luck on the next level.

Had the same problem wondering if this is because I played some of the cruel difficulty with the same char and Mabey
already got "this" reward on some other boss.

This is the second boss that hasn't dropped for me, im down 4 skill points now :(
