I've not been to the secret unicorn level myself yet, but what I read about it makes me wonder if Blizzard tried to create a parody of My Little Pony: Friendship is Magic.
I remember seeing teddy bears on youtube playthroughs of it. It's more a parody of the sugary kiddy-genre in general than any one series, as well as mocking their critics who felt their expanded color repertoire in the previous game made it more kiddy despite the increased gore. Besides, Diablo 3 had been in development for nearly 11 years, they probably had something like this planned for years.
It's cause people criticized the game for looking "too kiddy" despite the earliest gameplay footage showed a barbarian being split in half and the game is full of gore. Course, they probably decided why not when My Little Pony became popular again.
It does have references to My Little Pony: Friendship is Magic. Why else would a Champion Monster there be called "Midnight Sparkle: Nightmare is Magic"?
Why does blizzard have Azmodan send a message (found on a messenger demon) to the effect of "We've successfully snuck into the keep. Stay quiet, and they'll never know", than proceed to tell the player anyway? Either one on its own would make sense (sneaking under the keep would show a flash of the tactical skill Azmodan theoretically has, telling the players fits with Azmodan's tendency to announce all his other moves), but doing both at the same time makes little sense. Closely related, I do wonder whether the writers themselves actually intended for Axzmodan to be a skilled commander, or themselves planned for it to just be reputation.
Well, it kinda makes sense as he's the lord of Sin. One of the biggest sins? Pride. So while he's got the premise down, his pride gets the better of him, and he just has to gloat. As for how he can be such a skilled commander with that mentality is a whole other question. Perhaps it's the Nephalem monkey wrench?
I'm gonna second Nephalem Monkey Wrench. I mean, while there is a great deal of pride involved in such a showcase, what general accounts for a One-Man Army single handedly decimating your forces. Hell, to his credit, I can see the taunts as his way of trying to "lure" you into your doom...I mean each of these hints ultimately leads to his generals.
Leah's skepticism about Cain's research is a big headscratcher. How can she not believe in all this stuff when she lives in Sanctuary, a world that seems to be constantly overrun with supernatural vermin? But if you pick apart her actual dialogue on the subject, it's possible that there's no contradiction. At one point she reminisces about having to drag her uncle away from some dusty old tapestries he was studying, because they were about to be attacked by an army of skeletons. In other words, she absolutely believes in the supernatural because she's experienced it first-hand.
Is it possible that the only thing she doesn't believe in is the potential for the Evils and the Angels to have another battle in Sanctuary? Her uncle's crazy theories all lead to the idea of another possible apocalypse. The moment when she starts believing seems to be when she gets proof that the stranger who fell from the sky is an actual honest-to-goodness angel.
The thing Leah specifically disbelieves is the End of the World prophecy, which is reasonable; demons have been invading Sanctuary almost constantly for millennia, so why should this invasion be different?
After the final battle with Diablo, we can see him being thrown down from the High Heavens, dissolving into dust until only the Black Soulstone remains, which will prosumably fall down to Sanctuary like Tyrael did at the beginning. Now considering that the witch Adria just disappeared after summoning Diablo with the stone and an offspring of Diablo, who says that the Dark Wanderer didn't have more than one child, so that she can just pick the Soulstone up from where it has fallen and repeat the process? Wouldn't it have been smarter for the Angels to hold onto the stone? Truly the last deed of Justice, not the first deed of Wisdom.
Reaper of Souls trailer shows that Tyrael has retrieved the Black Soulstone and sought to hide it.
A lot of players have erroneous assumptions about the topography of the series' cosmos. Sanctuary isn't directly below the Heavens, like the ground beneath the clouds. If it were, the angels wouldn't have had so much difficulty finding it. It seems to be a planet on a distant realm far from the Heavens, and possibly on another plane of existence. When the Soulstone fell from Diablo in the end cinematic, it didn't fall to Sanctuary; it probably landed on another platform lower in the Heavens.
How exactly did Tyrael become mortal? It's not like all angels have a "become human" button somewhere on their armour. Humans are explicitly the spawn of angels and demons, so to become one he'd need demonic influence. Just stripping his wings might remove his angelic power, but it shouldn't have made him human.
Actually, an angel succumbing to demonic influence doesn't turn them into a human, it turns them into a Corrupted Angel. So even with demonic influence, Tyrael would be, at best, a demon himself. As for exactly why he becomes a human instead, I dunno. He is clearly the first angel who has ever removed his angelic powers, so there is no precedent for how that magic works. It seems that his angel powers are what grant him immortality (mostly immortal, at least, his body can be destroyed, but he'll eventually reform). So, perhaps, with that gone, he just sort of defaults to human, because "not-immortal" = "mortal". Sorry if that's kinda WMG, but again, we don't know exactly how it works, there's no precedent.
The why is fairly simple. It's a combination of fully releasing himself from the oath that prevents him from interceding directly on humanity's behalf, and just being sick and tired of the Angiris Council's inactivity as Sanctuary, and humanity with it, are slowly being destroyed by the forces of Hell. One can assume most of his actions prior can be explained either as loopholes, or just a premise of "easier to beg forgiveness than ask permission." Hell, it was a spat with Imperius that prompted the "Screw this and screw you" reaction of stipping himself of his angelic status.
Considering that Malthael spared him after examining his soul, it seems that he has a human's appearance but not the demonic taint. Answering "how?" and "why" probably needs more info than we have.
Pretty sure the word you're looking for is "mortal". And indeed, it's basically confirmed by Tyrael himself later—he's mortal now, but not nephalem; he lacks the demonic influence common to all humans.
I think that although the cinematic implied that an angel stripped of its powers becomes a human, he instead used his angel powers transmute himself into a mortal that only looked like a human, for some reason stripping off his wings (which are the main part of an angel's body in Diablo) to do so.
What exactly are the Monk's (and other classes) gods and spirits? When we go to the High Heavens, we only see angels and such. It's possible, one supposes that say Ytar is an angel or non-existent, but both Monk and Witch Doctor both get (or believe they do) get their powers from said beings. One could say that perhaps they're just channeling their nephalem powers (they being the first generation born after the worldstone's destruction), but then where did their predecessors get their power? And it still doesn't explain who beings like Ytar actually are.
The angels don't exactly seem to be the gods of humanity. Anu and Tathemet are nearly confirmed as being real (but dead) gods, with their corpses becoming the angels/high heavens and the demons/hells respectively. So if the high heavens are a dead god's corpse, it makes sense that we don't see other gods living there.
Bastion's Keep deaths
How did all the characters at Bastion's keep actually die in act 3-4? (There's no actual battle that occurs, so it makes little sense for the soldiers to get killed unless they went to watch the transition event and got killed as part of that process.)
Is this as you enter Act IV? Well, Adria is a powerful witch serving Diablo and a traitor, so I wouldn't be surprised if the guards were celebrating when she suddenly attacked.
Assuming they weren't outright used for some manner of blood magic to make this work. Hell, I'm pretty sure the circle Leah and Adria were standing is was drawn in blood, so...yeah...
Seriously, why the hell do you need to get it? I mean it's not like you use it to barter safe passage, as they open the gates and rush you as soon as you arrive with it, so why not just smash the gates in the first place, and charge through, aside from the fact that they needed to justify a speed bump to force you to explore the area?
If we have to explore why the hero isn't able to smash these gates down, we'd have to explore why the hero can't smash any similar gates down. (Quite frankly, I don't think about that, and neither should you.) Really, the way I saw it, the hero's possession of the staff provoked the khazra into attacking (to take it back). I seem to recall at least one of the khazra shouting "the staff is ours!" or the like.
There's no in-universe explanation for this, simply because its existence as a dangling thread is due to production difficulties: Getting the staff was SUPPOSED to be part of getting the Mystic artisan, in the form of the young woman you rescued from the spiders, but things got messed up and they had to cut the Mystic from the initial release - leaving the first part of her quest dangling in the form of the Khazra Staff. It took until Reaper of Souls for them to get the Mystic all sorted out, so apparently, it was really hard...
What is the deal there? I mean that is a seriously wild Retcon, going from an extraordinarily proud angel who bungled an assault on Mephisto, and ended up being mutilated into being the progenitor of Overseers while being trapped in a mirrored room to being a refugee with Lilith, and the progenitor of humanity itself. I mean I could see making a tale up as a cautionary tale to other angels, but, I mean...it seems to be lining up to be the worst kept secret ever if that's the case.
So... what's all this I've been hearing about "Legendary rain" or "Guaranteed legendaries"? Because I've not found a single legendary and I've invested about 40 hours into the game (Post 2.0, I have roughly 65 logged from 2012). Only about 20 of those were on Torment. Does the RNG just hate me that much or am I extremely unlucky?
Yeah, it seems like the RNG does just hate you. Even on Normal difficulty, I've been getting legendaries every few hours. Diablo himself dropped four of the things! It's a little ridiculous, honestly. I got absolutely no legendaries for the first year-and-a-half of owning the game, then 2.0 comes out and I get ten within a couple days.
Apparently it hates me - I'm playing with my friends who're flat out tossing legendaries out. I've gotten five. Why on earth do I have such terrible luck?!
A better question to ask here: Do legendary crafting materials (See: Forgotten Souls) count towards a "Legendary" count? I'm practically bleeding Forgotten Souls.
Malthael's brilliant plan
For being the previous Aspect of Wisdom, Malthael's done some incredibly stupid things during the Reaper of Souls expansion. His idea to bait the Nephalem and lure him/her to Pandemonium was ultimately what gave the Nephalem the powerto defeat him in the first place. Why did he not simply hunt down the Nephalem right away? He/she wouldn't have been able to touch Malthael at all, and all of Sanctuary would have been his for the taking. But no, not only did he set himself up for ultimate defeat better than any of the good guys could have hoped for, he also shattered the Black Soulstone and took the powers of the Prime Evil for himself in a last ditch attempt to destroy the Nephalem! That monumental hypocrisy aside, his death released all Evil back into the world. Dear god, someone get that Idiot Ball away from him.
It could be possible Fridge Brilliance: Malthael wasn't always the Archangel of Wisdom, and in fact may have never truly been Wisdom. He started out as Death; in essence, Reaper of Souls sees him returning to his 'true' form, so it stands to reason he'd make some unwise decisions.
He also didn't exactly 'bait' the Nephalem to Pandemonium - if anything, he did his best to hide there, effectively seeking out the single-most remote, isolated, and well-defended location in all of Creation - and then attempting to destroy the only way to get there. Reaching him required you to first seek out an extremely powerful witch capable of tracking the location of the stolen Soulstone using a (from the looks of it) VERY demanding Blood Magic ritual, then beat Malthael's strikeforce to the gate (by minutes at best), then powering up some insanely powerful siege-weaponry to even get inside. One might argue that it was still unwise for him to hang around directly on top of a source of power that could be turned against him, but it's never made clear if that 'Power of Death' thing has ALWAYS been there, or if it's simply manifested there because it's where Malthael is - if it's the later, it would've formed ANYWHERE he tried to hide, and Pandemonium Fortress was basically his best bet for both staying hidden and keeping the Nephalem from reaching him in time.
