Whether you invest Sigils of Despair (node in Sigils of Hope tree) or not, Divine Flare is modified by increased Fire or Void Damage you have or,
affected by Fire or Void flat spell damage you add.
Same goes for Smite.
Not matter you invest in Temporal Corruption (Void Knight passive) or not, Smite is affected by both Fire or Void flat spell / increased damage
Tested with several unique items (Blade of the Forgotten Knight and Volcanus for added spell damage; Rahyeh’s Light and Defiance of the Forgotten Knight for increased damage)
Also tested with Alluvion (addaptive spell damage). Seems this addaptive spell damage will be the type of the tag the skill has.
If I think I understand what you’re saying, neither of those two damage conversions convert added damage. Temporal Corruption says it only converts Smite’s base damage, so any non-adaptive flat added damage retains its element and hence would be affected by the relevant % increased damage.
Sigils of Despair says it converts the flat added fire damage that Sigils provide to void, it doesn’t mention anything about Divine Flair’s damage being converted, though it would be nice if it did convert that as well.
Adaptive spell damage does, as you say, adapt to the elemental damage tags of the spell.
Flat added spell damage will always affect a spell, regardless of the spells tags. If a spell has multiple damage element tags (like the default Disintegrate’s fire/lightning) then any adaptive spell damage is split equally between them.
Didn’t know this. And now I understand.
I was always wondering why melee attacks can have a different element flat dmg added to it without tag of this element while spells cannot. But that’s not true, it’s just I always use adaptive spell dmg affixes
It’s good to learn this. Thanks for the explanation
