Archetype EMIYA

Okay, so I'm going to do a semi-realistic assessment of what to do when confronted by a Servant who's out to kill you. Well, more in this case me, but I'll apply it to the reader's situation as well.

First line of defense, as is common sense, is to have your Servant around! When you're dealing with the aforementioned Heroic (bah) Spirits, the best Servant to summon against these would be a Saber as well. Have them deal with it! You're just a human... right?

The topic today concerns these three. Let's start with the one that's hopefully the easiest to deal with.

First off, if you even suspect that Semiramis is around, don't breathe, don't drink anything, don't eat anything. Her signature weapon is poison, after all, and the mere fact that we still don't know what her Noble Phantasm is means that we can't deal with it yet. However, poison is only poison, so in this case I'd recommend carrying around something like a gas mask, or a Ribbon, in Final Fantasy terms. Though she's bound to have the good stuff, like CON poison which directly saps your life energy or some such.

Basically, kill on sight. She's cunning, "deadly and sly", and you do NOT want to get killed by her. Run the fuck away if you have to. If she appears in front of you, kill her as fast as you can. A holy sword or purified bullets should do the trick.

I still can't believe that any Shirou would even summon her.

Next, someone we're more familiar with. Nero. That sword should have been enough of a giveaway, really. There's really not much you can do against a self-professed Emperor who can and will do what she wants. She could fuck you over and you'd like it. Again, your best defense is sicking your Servant on them.

The more troublesome aspects of Nero as a Servant would be the ability "Thrice-Setting Sun". She just doesn't fucking die that easily. Besides that, the Aestus Domus Aurea - a Reality Marble that allows no escape as she carves you up. Her "performance", so to speak.

Again, holy sword or bullets should do the trick. Though that's stupid of you to face a Saber-class Servant in direct combat like that. Still though, better to die fighting that be killed.

Lastly for today, Mordred. Dear God, this is a tough cookie. Imagine Nero with Prana Burst, that's basically what you're up against. She doesn't die even if she's killed. She was impaled and still managed to land a deathblow, dammit. The very part where she launches herself at you with a force enough to pulverize a tank...

In any case. It has been shown that Saber-class Servants aren't exactly invincible even to continuous machine gun-fire. Saber herself had to keep moving lest she get hit by Lancelot's machine gun. Now, I am aware that that was technically a D-class Noble Phantasm, but if that is the case then you get a gun that's considered to be a Heroic Spirit! Something famous like the AK-47, or the M1 Garand, something that's seen a lot of action and taken a lot of lives.

You're just a human against a Servant, you do what you can to not get killed. Guns with holy bullets should do the trick against these. If you're feeling ballsy use a holy sword, but honestly I don't think you're that stupid.
