Say if i have a weapon that deals magic damage instead of physical damage. That weapon then has a magic or faith parameter to boost the damage via the faith or magic stat. Does strength and dexterity then not effect the weapon damage in any way? would magic and faith be the only way to increase that weapons damage?
Depends on the item. Easiest way is when lvling see what stats also have increase attack. Faith says increase attack then yes faith effects it etc. Some have mul;tiple stats but how mixed do you want your stats to really be..
