The change to ancient knowledge is a little unclear: the new passive says that inferno staffs buff your damage with single target abilities by 8%, while the lightning staff buffs your AoE abilities by 8%.
The passive does not affect:
Light and heavy attacks.
Set bonuses (I tested with grothdarr, illambris and malubeth).
I made this thread to collect data as to assess which skill benefits from which passive. Some abilities, such as velocious curse, have an AoE component and a single target component. Just comment your testing results and I will add them to the OP.
In the end, you can determine which weapon is better for you depending on the percentage of skills that get buffed by the respective weapon.
