I agree definitely about the fact that the "Brain of God" runes does have a difference in power compared to the "Gandalf". Perhaps the "Brain of God" runes on Sheffield are more into casting and using magic items which is mostly void magic while Saito's "Gandalf" runes are more focused on melee weapons allowing him to fight with a melee weapon much better then usual melee weapon training without the runes. However it seems that the Gandalf runes are more suitable for Saito's talking sword derflinger as Saito fights pretty well with derflinger when he has his runes on.
Im sure Tiffannia is a void user too and might have not known it yet. It was interesting to hear that she revived Saito with her Void magic so I guess it can't be anything else. If Tiffannia was to summon a familiar, its possible that it could be another Gandalf or another "Brain of God" but im sure the void powers from the summon will be similar in comparison to Sheffield's and Saito's runes and void magic.
Sheffield does look more intellegent therefore resulting to have the "Brain of God" runes while Saito is more focused on protecting the ones close to him, mainly Louise so he ends up with the Gandalf runes. So perhaps it depends on the characters personal traits and interactions which result in the type of runes they get when summoning a familiar as a void user whether its close combat or more experience with void magic. |
