Seeing an Overlord nigga basically expose himself live showing he knows jackshit about Fate... pretend he knows about Fate and how Nazarick can defeat him is absolutely hilarious
[Pelt of the Divine Beast] is basically the primary reason Alcides is dangerous since it makes practically all other NP's ineffective against him and is the primary reason he could give Gilgamesh a run for his money. Powerful enough NP's can bypass it if they strike areas not covered by it, but Alcides still has a degree of protection. However it is completely ineffective against unarmed attacks, magic and magically augmented physical attacks/abilities. I could argue that the weapons from Yggdrasil are not "The works of man" and thus it shouldn't function against them. However I'll put it aside and say it works more like Ainz's High-Tier Physical Nullification, but a-specifically against offensive weapons.
Nope, Magecraft explicitly can't work against him either and Yggdrasil's systems was made by human hands and thus, no, nothing in Overlord outside of Wild Magic would do shit to Alcides. I highly doubt anyone can hurt Alcides in Overlord because they was made by human hands before "becoming real".
[Nine Lives] is hard to quantify since it apparently has many forms and uses. Mainly apparently he can control his arrows. Should reiterate that Nazarick itself can't be destroyed.
Casual use of NLF... Nazarick can be destroyed, just nothing in Overlord can do it but considering how weak that series is, that doesn't mean much at all.
[Reincarnation Pandora] allows Alcides to steal an opponent's NP. This is effectively useless. He's not stealing any abilities here. Not only are the conditions for this not fully explained, but none in Nazarick have NP's nor does Alcides know the names of any of the weapons/equipment from Yggdrasil. He's not stealing anything ladies and gents.
REALLY shows he hasn't paid attention to a single thread when he(like the others) keep repeating the same goddamned mistake over and over again...
Alcides' Reincarnation Pandora can steal more than Noble Phantasms, this is why you shouldn't take what a character says at their word because their word alone doesn't mean jack and shit... oh right, it's only convenient when it benefits SB members, my bad.
[From Hell] isn't a NP Alcides starts with and is one he stole from Jack the Ripper. While I personally don't feel it should be allowed since it's not part of his standard power set, it's essentially a transformation that raises all his stats and defenses in proportion to the amount of fear generated by others within a 5km radius. I would argue it's not very effective given practically everyone in Nazarick has either protection against Fear or such effects, or are undead and don't have such emotions. So I'd argue it's effectiveness against Nazarick is extremely limited.
"This shouldn't be allowed" GTFOH. It's up to the user if they will allow certain things or not but don't pretend that it should suddenly benefit you that certain things shouldn't be allowed either(Seriously, the number of times I see the same shit in SB with Servants is enough to drive dudes insane). If he has From Hell, he has From Hell, cased closed. And no, From Hell only increases the amount of Doppelgangers he creates, not the amount of power he has... not like it matters.
[Stymphalian Bird], [Mares of Diomedes] and [Cerberus] are basically summons. Nazarick has tons of ways to either eliminate them or outright bar them from being used in the first place. Like the spell [Greater Rejection] Ainz used to keep Shalltear from summoning 10th-Tier Monsters. These're ultimately moot.
Suuure, they have a way to deal with Cerebus... this being right here:
Here, An Atlantis Guard states that it's wasteful to use a Demonic Beast like
Cerberus that can hold back 10,000 of their ships(Each one can deal with the Golden Hind powered Argo in a head on fight) just to blow it up and take out the island through overloading it's Klironmia.
Even if Alcides' version is weaker due to it's Divinity being removed... it would still be above Overlord's level to deal with it.
And that's pretty much it. If there are others I don't know them or can't find them. Just looking at that, I don't feel Alcides can win. Not against the whole of Nazarick. That's suicide. He has A-Rank MR, which means upper-tier spells and above are all effective against him. Which includes [Meteor Fall], which we'll hopefully get to see this year when they finally show the Overlord: Holy Kingdom Arc movie.
I never can understand this at all... Overlord_Rei acts as if Servants haven't dealt with shit like this before when Magecraft is hilariously above everything in Overlord past their Death Hax(And that's only due to it being within AoG-Tier Magecraft which shits on everything in Overlord) and then act like Servants will just die in 2 minutes without Magical Energy when:
1. There have been numerous times where Servants have had high grade battles without any sort of Master and was still around after it... Shirou literally fought a less than 1/10th EMIYA, got destroyed and he got wrecked by Gilgamesh and still lived to eat some animals and wreck Gil's shit in. We have seen Rogue Servants only having their own Magical Energy supply last damn near FOREVER and only vanish on their terms and the FGO America Manga has Karna and Arjuna fight for god knows how long despite being long cut off from magical energy supplies and they could still fight for 10 minutes more after that and both are known for being mana guzzlers.
2. Alcides, as well as any other Servant, can just devour the fallen of their souls and magical energy to keep their existence around if they need to... it's not like they have to spam anything major to kill the grunts as if they have feats because "we are told in this passage here" like it means anything
3. Shouldn't Alcides have access to the huge Mountain of Pure Mana Crystals Bazildot connected him to? That will keep him around for 6 months and nothing has stated that Alcides has worn it out massively by any degree which only proves further how ridiculous this "Servants can't last in a long battle" cope is.
