I'm just currious about Saber and the Excalibur. Alright, from what I've read, Excalibur is the sword we see Saber wielding throughout the series, just most of the time it's wrapped in a hyper wind vortex that glows ethereal blue? Right? So, is the sword always tangible and physically with Saber? Or does she summon it to her like she does her armor? Furthermore, what was the entire deal with her expending energy to summon the sword in the battle with Berserker, when the sword was already there in her hand? Does it have to be unsheathed of the invisible wind to charge up and attack? Or what?
