Damage done by you or your summoned demon has a X% chance to increase the damage done by the other by 10% for 15 sec.
How you get it
No trainer level in the client data
The tables we read record no trainer level for Grimoire of Synergy. That usually means it comes with another ability, a talent or a quest rather than a level-up visit to the trainer; we have not confirmed which in game.
In Season of Discovery, Grimoire of Synergy was a rune engraved on gear. In Forever it is an ordinary Warlock ability, one of 9 former runes the class keeps.
An “X” in the description is a number the client text does not resolve; the real value is only visible in game.
