... It is said in the VN that Saber wasn't able to take spiritual form because of shirou not being a proper master... but then is revealed that Saber was still dying at her time when she was summoned in the 4th and 5th war... then i wonder, if a human (not a magus) master summons a regular servant, could that servant take spiritual form?
