Magic scroll, but caster was not in spell's tradition

[Laclale♪]

The casting to craft scroll must come from a spellcaster expending a spell slot.

Crossblooded Evolution can have have one spell in your spell repertoire from a tradition other than the one that matches sorcerer's bloodline. And can cast as a spell from sorcerer's bloodline’s tradition.

So if said sorcerer casted spell to craft scroll and who doesn't know that spell to identify, what kind of skill can use Assured Identification?

[Blave]

I'd treat such a scroll no different from a regular scroll of the same spell.

The fact that the sorcerer can treat the spell as part of their tradition's spell list doesn't add the spell to the list in general.

So if a demonic sorcerer crafts a school of slow, the skills to identify it would still be Arcane, Occultism and Nature. The sorcerer can still use the scroll himself as the spell is part of his divine spellcasting. That does not turn the spell into a divine spell. It's just part of his class abilities.

And Crafting if having Crafter's Appraisal skill feat as scroll is item. This can be applied to Shape Stone from Pleroma's Divine Innate(Wait, Innate can't cast to scroll).

So Arcana caster needs feat like "trick magic item" to cast Heal from scroll, as Heal is not in Arcana list.

Scroll tradition is determined relative to the caster, not the crafter.

There are no arcane, divine, occult, or primal scrolls in this edition, only magical scrolls. It doesn't pick up the above traits until it is cast, at which point it adopts the most appropriate tradition trait for the caster (assuming the spell is in itself from an appropriate tradition that can be cast by said caster at all).

[Jared Walter 356]

Ravingdork is correct. Scrolls have the magical trait, and no tradition traits. You can identify the spell on a scroll with any of the skills: religion, occultism, arcane or nature. Regardless of the spell on the scroll.

When cast, spells (even those from scrolls) gain the tradition of the caster (and only that tradition). If you are a divine bloodline sorcerer, all of your sorcery spells are divine.

Magical Tradition wrote:

In some cases, such as when a cleric gains spells from their deity or when a sorcerer gets spells from their bloodline, you might be able to cast spells from a different spell list. In these cases, the spell uses your magic tradition, not the list the spell normally comes from. When you cast a spell, add your tradition’s trait to the spell.

when a spellcaster uses a class feat or ability to gain access to a spell that is on a different tradition spell list, that spellcaster treats the spell as being on their normal tradition.

So your example of Sorcerer using Crossblooded Evolution - the spell from the other tradition would still be treated as though it was on the Sorcerer's normal tradition. An Arcane Sorcerer that uses Crossblooded Evolution to learn the Heal spell would be learning and casting an Arcane version of Heal rather than the normal Divine or Primal version of Heal.

This isn't the only example of this. Witch has Lessons that give them spells of various traditions. Cleric Domain spells are always from other traditions.

This reassignment of spell tradition doesn't happen when you use an archetype to gain a new spellcasting class, or for innate spells from ancestry.
