Does the “+% Damage” perk add damage to both attack and rune damage or only to attack?
Rune damage entirely scales off of weapon damage. So theoretically, anything increasing weapon damage would increase rune damage. I’d test it yourself though.
Really? Rune damage scales off Weapon damage?
Does it scale only for melee weapons?
Because when I tried with wands/staves they did the exact same damage even though staves have higher base damage.
That I have no idea on. Just that when I upgrade my weapons rune damage rises with it. Otherwise all runes would just drop off a cliff with level.
