One of my thoughts is that staves could add their elemental damage to the damage done by spells of that element, but that runs into the problem of tenebrium again...
Maybe a theoretical tenebrium staff always adds its tenebrium damage to any spell of any element...
At the very least, mages would have a reason to upgrade their staves.
That would require extensive work.
I'm here thinking worst case scenario, we'd have to make the mods ourselves. This would mean we'd have to rebalance all the spells for weapon bonus on top of adding new calculations to determine net spell effect. Lol do you have an easier idea to implement?
It seems the only people interested in this is us two?
Maybe I should have made the title more salacious?
"Worst game ever! Tenebrium broken! Needs fix now!"
