Well this is going to be long.
"Because it is explicitly the most powerful Noble Phantasm in terms of destructive output, period."
Ea is literally never said to have the highest destructive output, next time post source of what you're saying. Here i'll quote materials:
"It's true power is not something to be used against a single living creature but against the world. Even among the many Noble Phantasms possessed by Servants, it is one considered to be at the top, the sword "which tore apart the world". "
As it says there, Ea's true power is being Anti-World, this is not DC but HAX.
And Excalibur is said to be equals or slightly weaker than Ea in destructive output(you know, those colored laser beams they shoot, the things that actually blow things up) as I already posted. "The space-cutting technique fired from this overloaded state is called "Enuma Elish", and boasts destructive power on the same level as Excalibur." By the way, both Ea and Excalibur have the same max number of targets(1000 people)
Why does one count and the other doesn't? You're not making any sense here.
"This includes the likes of Anti-Country Noble Phantasms like Karna's Brahmastra Kundala and Arjuna's Pashupata, which is potentially even stronger due to being the single most powerful weapon in Hindu Mythology.
Nothing in the Nasuverse short of Avalon and maybe Lord Camelot (and Akasha obviously) can take a full power Ea since it shows the "Truth", like Slash Emperor, which is powerful enough to take down Archetypes, who are far above the likes of Kiara, who grows larger than a planet as part of her Noble Phantasm."
Except Excalibur is said to have the same destructive output(again, laser beams). So what you're saying is wrong.
And Again Ea is never said to have the highest destructive output, showing the truth of the world is HAX not DC.
"In addition, according to the Type-Moon wiki's account on Ea and Fate/Strange Extra, he only other case in which Enuma Elish was used at full power was during his fight against Enkidu, in which the world was indeed pulled apart and put back together by their respective versions of the attack."
The world being pulled apart is not DC, it's HAX. Ea destroys worlds, doesn't mean it blows things up like a bomb, not DC. And what TM Wikia says about is being the "only case" is not canon since they're a fan page, the VN and Materials are canon and word of god. Also, in Extra Gilgamesh was boosted by Akasha, that's not his original power, they're called Origin Boosted Servants for a reason.
In the VN(as I already posted) Gilgamesh used max power Ea, in the Materials it SAYS that Ea's DC is equal or slightly higher than Excalibur's.
To repeat it again, Ea is not about blowing things, it's about Hax, that's why it's a top NP.
"Finally, Shirou NEVER traced Excalibur outside of the Normal End of the Heaven's Feel route."
I never said anything about Shirou tracing Excalibur outside of Heaven's Feel, next time actually read the thread before posting, it makes things much easier.
"Saber was indeed holding her own Excalibur in the route you've specified (meaning Fate) and is thus the original and at full power."
Except in here it clearly says that Saber's Excalibur is not full powered when under Shirou, i'm just going by what's written in her profile,"She was plagued by a lack of mana during the aforementioned examples, a fully charged Excalibur is likely to be far more powerful". Excalibur is a sword that converts the user's Mana into energy and shoots it, Saber being under Shirou makes her weaker, in the final attack against Gilgamesh she turns her own Armor into Mana in order to make the attack more powerful.
So again, an uncharged Ea is not stronger than a full powered Excalibur as said by several materials.
I'm out now, need to do some things, still the materials and VN pics are already posted so I don't really need to post anything else, it was fun debating though. If anyone feels like contradicting the VN and Materials then I certainly can't do anything about that so I'll just try to not make the thread unreadable and too long when all that's necessary is in the first posts..
