I just respecced my warlock to Affliction and picked up Grimoire of Sacrifice as one of my talents.
The description says:
You sacrifice your demon to gain one of its abilities, increase the power of many of your single target spells by 50% and regenerate 2% of maximum health every 5 sec.
and I can't seem to figure out the demon ability part. I assume it varies per demon, but which ability do you inherit from which demon? Should I just drag one of the demons' abilities to my action bars?
How do I make this thing go?
