¿Is the intent of the updated Break battle spell to be ineffective against Ritually affected weapons (e.g. a sword with Elemental Imbuement), but to affect Ritually affected armor (e.g. a suit with Armored Shell)?
While enchanted armor cannot be broken by the Break spell, it still reduces its value to 0. So you can refit the armor immediatly without mending it, but its still reduced to 0.
Yes. Non-magical armor would be Broken, and as part of that reduced to 0 points.
Repairing it does not intrinsically refit it, so it would need to be refit separately.
