Literally in the patch notes: Get immediate access to the new Macrotechnic Epic Destiny with any edition of Vecna Unleashed!
Yeah but, no but. Bought it, relogged twice, reset all my trees. Still can't spend any points in it. I'm level 25. You going to tell me that I need to be lvl 20 to spend points in it or it's only available after a TR?
Did you go to the Junction of the Spheres and talk to the guy to unlock the tree?
