Seeing Shirou so poorly armed, you toss your Sword of the Planes to him so he would stand a chance, "Shirou; catch!"
Hearing you call out, and seeing the sword; Shirou tosses aside the pipe and grabs the blade, then proceeds to go to town on the shoggoths with it. Since they're from...some twisted world or another, the sword is empowered by the enchantments on it. Not to mention that it's probably even stronger since you're on a different plane than any you've ever heard of.
Meanwhile, you also fight off the horrors from the abyss; using your rapier to slash at the tar-like beings and setting them on fire with a fireball or two. Thankfully, your rapier is capable of slashing
and stabbing; unlike most normal ones. Had it custom made to be like that, just for situations like this.
God, oozes are always a pain in the ass to fight; stabbing does nothing, smashing only spreads it all over and that usually means acid to the face for everyone, and slashing only breaks them up into smaller chunks. Obviously slashing blows are the most effective, being basically controlled smashing of the ooze, but it's not by much.
What's even worse is that these fuckers are made of
tar, or something like tar; which is hard as
balls to get your sword through. But thankfully, that's where Rider came in: her eyes managed to solidify the things-that-should-not-be enough so that your sword wouldn't be jammed in their bodies. Plus, the chunks that did come off turned to stone; which made the chances of them pulling themselves together rather slim.
Even with these advantages; it was a though fight. The monsters could warp and shift their bodies to any form, far more than any ooze or slime you've ever fought. Some even took on your form; and man was
that creepy as fuck. Not to mention there were twelve of them and three of you; being outnumbered
always blows. Oh, and the whole 'every second you look at them your mind breaks'; that sucks too.
But you managed to put them down, and keep your sanity; Rider smashing them with brute force and her fists when her dagger proved useless. You with fire and flashing steel. And Shirou, man was
he kicking ass; he managed to make a
second Sword of the Planes and was chopping them down faster than a dwarf chugs ale! Kid seems to be good with two swords at a time, though it almost seems like he's being...guided in his strikes; like he was copying the movements from someone else...
Eh, whatever; time for that later, ritual busting time now! When the last abomination falls, you rush towards the ritual circle...
...Only to be thrown back in a blast of power, as the body floating within turns hit empty, soulless gaze at you.
Yes! I can feel it! The essence of the master flows through me! I, who possess the gift of many forms, am graced to be reshaped in his divine visage!
Issei had become a
monster; his shape constantly shifting as arms became tentacles which became faces locked in terror only to turn back into tendrils and claws once again.
The former human's face was a in a mix of bliss, terror, ecstasy, and agony; you couldn't tell if he was smiling, or grimacing. Or both. His eyes were filled with both terror and worship, and his body was wracked with convulsions of both pain and pleasure.
I am one with the Crawling Chaos! It hurts, but it is a good pain...
He turns to look at you, his form still ever-shifting. Pointing a...forelimb, he utters out,
Now you shall fall before the might of Nyarlathothep and know the futility of your defiance!
Then, he; or rather it, begins to gather dark energy into it's tendril...claw...things, ready to fight and kill you.
...Fuck, this is gonna suck...
Tactics:
[X] Evasive:
DODGE!!!! Stay light on your feet and pepper it with pot shots, at least until you can find a weakness.
[X] Offense: Attack and don't let up; don't let it even get off a single attack and you'll eventually turn it into paste
[X] Diversion: Be offensive and loud, and keep his attention on you so Rider and Shirou can hammer it with sneak attacks
[X] Write-in
Notes: I would've put Issei's text in zalgo; but that doesn't play nice with the forum...
