Spell damage aint working with WDM skills , it increases tooltip damage but that bonus damage from spell dmg counts only for melee swing attacks.
thats odd cause I just tested it... again, and it clearly works with stag bow, alot of pple use spell damage only gear with elemental bow too
and not because their damage isn't boosted by it lol, but because it's easier to get damage from that source as opposed to dex gear in the early game
it doesnt make sense that it works with innate damage melee weapons
but not innate damage ranged weapons either
then u want to focus on dex+deadly strike+innate+ all your other necessities
It is not a question of it making sense, it is a question of the diablo2 engine. Spell damage has always worked with flat damage sources on melee attacks and not on ranged attacks, even in vanilla diablo2. That is why melee sorcs using the enchant skill were a thing but bow sorcs using the enchant skill were not.
But since you claimed that you tested it, I was swayed and tested it myself too.
I wasted a belladona, respecced my druid and tried the following:
I punched monsters in nightmare bloodmoor in melee and with the throwing attack using a sacred throwing axe and also shot them with a sacred maple bow without having points in any skills.
Then i put 27 points into pagan rites, giving me 135% spell damage. The tooltip damages (both melee and ranged) went up as expected.
Back in the bloodmoor, monsters were still taking the same amount of hits to kill with ranged attacks.
On melee attacks, however, everything was dying with one hit now.
This is clear evidence that spell damage does not scale innate elemental damage on ranged attacks.
On melee attacks, i am unsure whether it scales innate ele dmg or just the flat ele dmg also contained on the weapon.
Also, deadly strike does not work with innate ele dmg according to devs. I'm not gonna test this, because it is too much work to isolate deadly strike on gear/skills.
