I'm fighting a monster with "Damage resistances: Damage from spells"
Can the feat Elemental Adept overcome this damage resistance?.
For reference, I was using scorching ray with Elemental Adept (Fire) and I'm a draconic sorcerer.
Technically, "damage from spells" is not a "damage type", and so these rules don't seem to interact with each other at all.
From the Elemental Adept feat:
Spells you cast ignore resistance to damage of the chosen type.
Certain creatures, like wizards of the abjuration school, can gain resistance to all damage done by spells. Since this isn't a resistance to a damage type (they still take full damage from non-spell sources of every type), then Elemental Adept doesn't seem to affect this in any way.
But ultimately it's up to the DM.
As Apocolisp indicated in their post it is indeed up to the DM on how to interpret that rule. I can see it both ways but leaned to Elemental Adept working in your example.
That said, although JC's Tweets are not considered gospel truth anymore (and for somewhat good reason), it seems intended that should and would work.
As shown in this tweet it seems intended that it would bypass all resistance that would reduce the chosen type.
The intent is that Elemental Adept bypasses any resistance that would reduce the chosen damage type.
I've changed my mind about this since my previous answer.
Damage from spells is always of some type. What if we take resistance to "damage from spells" and just expand it slightly to be more explicit:
Resistances: All damage types, as long as the source of the damage is a spell.
So if the Elemental Adept is casting a spell that causes damage, then the creature is resistant to that damage no matter what type it is. Ergo, the resistance can be ignored as long as the damage is of the chosen type.
