CRB pg. 459 states, "Magic items produce spells or spell-like effects. For a saving throw against a spell or spell-like effect from a magic item, the DC is 10 + the level of the spell or effect + the ability modifier of the minimum ability score needed to cast that level of spell."
But if the spell is one that is a different spell level for different classes, how do we determine which class to use for the above calculation?
I've heard many conflicting answers for this:
- Some people say you should use the class of the crafter of the magic item. But what if you do not know who crafted the item?
- Some people say you should use the class of the person activating the magic item. But what if that person is not any of the classes that has the spell?
- Some people say you should always assume sorcerer/wizard. But what if
sorcerer/wizard is not any of the classes that has the spell?
- Some people say you should always assume the class with the lowest spell level.
- Some people say you should always assume the class with the highest spell level.
Does anyone have a canonical source that clarifies this?
