In the 2024 PHB, sorcerers get Innate Sorcery. The text for it reads:
[for the next minute] You have Advantage on the attack rolls of Sorcerer spells you cast.
I'm interested in the restrictions of "Sorcerer spells". If a multiclassed Sorcerer activates Innate Sorcery, what spell attacks (cast in the next minute) would not benefit from Advantage?
Please note there are a few scenarios to consider:
- A spell that is only available via multiclassing but cast using shared spell slots. For example, a cleric/sorcerer casting Guiding Bolt or a warlock/sorcerer using Eldritch Blast.
- A spell learned via the multiclass, cast using a shared spell slot, but available on the Sorcerer spell list. For example, a warlock/sorcerer that learned Firebolt as a level one warlock.
- A spell learned as a sorcerer but cast by a warlock/sorcerer using a Warlock pact slot.
- Spells gained through Feats such as Magic Initiate or Fey Touched.
[Edited to add] Based on What makes a spell being cast considered to be a {class} spell?, the answers seem to be:
- Yes, if it's on the sorcerer spell list and learned as a sorcerer.
- No, if it's not on the sorcerer spell list.
- No, if it's on both the sorcerer spell list and multiclass spell list but you learn the spell via the multiclass.
- Yes, if it's learned from a feat that specifies it's a sorcerer spell (e.g. Magic Initiate).
