User blog:Muhammedmco/Fate Franchise - Saber Arturia's Excalibur Speed

Introduction
So I’ve been looking around through various sources, and I do believe that there is indicative information that Servants are far faster than previously ranked.

First of all, Saber’s Noble Phantasm, Excalibur moves at Light-Speed. There is direct narration from Fate/Zero’s Light Novel, The original source to indicate as such

Taken from Fate/Zero Act 10

Taken from the Fate Complete Material III Guidebook.

Taken from Fate/Grand Order Material I Guidebook.

Taken from Fate/Zero Material Guidebook.

Taken from Fate Side Material Guidebook.

Excalibur operates by accelerating Arturia’s attack into real light by using her Magical Circuits where are actually on the level of a dragon. Like other verses, Dragons are incredibly powerful and it makes sense why it would require this level of thaumaturgy skill to pull off the attack. Plus, magic attacks themselves are done to replicate the natural phenomena that occur in science and nature.

Calc
Feat in Question.

Rider, at point blank range was able to dodge out of the way of Saber’s Excalibur and escape into a nearby tree. This other excerpt from the Fate/Zero light novel tells us that the initial distance was 100 meters but when Saber fired, they were less than a meter apart.

Following the sequence of events:

-Rider charges forwards -Saber fires Excalibur and we see the light itself fly forwards -Rider reacts after this point where the light itself is already well on its way. -Rider ends up ends up in a tree above.

Now, onto the task of calculating this level of speed.

I’ll use the pixel scaling that Seraph used for the calculation now.

Arturia’s height = 426 px.

Iskandar height = 550 px.

Arturia height post escape = 106 px.

The two values we need are:

Distance between Arturia and Iskandar when Excalibur was fired = 0.273 m.

Distance Iskandar Travelled = 16.315 m.

Timeframe = 0.273m / 299 792 458 m/s = 0.00000000091063 seconds.

Velocity = 16.315/0.00000000091063 = 17 916 167 927.69840659763021205 m/s. (Mach 52 233 725.73673004657, 59.761903442208698323×FTL, or FTL+)

Now I’m sure that instinct is to go and call this an outlier, but there’s already a quote of Saber and Lancer’s fight nearing the speed of light.

Plus, if you look at the speed rating for Rider, he has a rank of D. This means that he’s not even average speed for Servants.

Conclusion
Saber Arturia's Excalibur Speed = 59.761903442208698323×FTL, or FTL+
