From what I’ve been reading digging into how spell damage is calculated:
Spell Damage + Atk from items - Enemy defense/resists + Element Bonus
There are other random modifiers that effect some spells and not others. But, that seems to be the core of the formula.
If the above is indeed correct the relationship between points you put into a spell and gear you wear isn’t multiplicative at all? Increasing your attack from equipment won’t impact your spells base damage and vice versa. Which basically means the two have no effect on each other. Is that right? Or am I missing something?
