Are reprints errata's?

[Grimserver]

Basically title. If a item/spell/creature/archetype/feat is printed in an older book, but then is also printed in a new book with alterations, is this new printing now the official version? Would this be considered an errata, or are there effectively now two versions of the subject in question?

[James Risner]

Ask your GM.

Often in PFS they will use one or the other. Fencing Grace they used the most recent. Scorpion Whip they used the oldest printing.

[wraithstrike]

The newest version is assumed to take precedent.

[CBDunkerson]

Could be either, newer, older, or neither... in roughly that order of likelihood. Ask your GM (or the PFS clarifications and resources documents) is the only 'correct' answer.

[Ascalaphus]

In PFS, all legal versions (according to Additional Resources) are legal. By definition.

If legal versions aren't the same, then you can have different versions of the thing. (e.g. Dueling property)

Sometimes they'll propagate the newer version of the thing so all sources use that (Fencing Grace). Only in that case is the newer version effectively errata.
