*Whoosh*

"GO! Let's see how you fare newbie!"

"Dammit! How the hell am i supposed to contend with that?"

*Boom!*

"Come on! A simple fire mage is enough to stop you? Hah! And you call yourself elite?"

"No! I don't! You do! And there is a fucking barrier of fire on the only entrance to that shitty cave! I can't see shit in the inside!"

"HAHAHA! If it was so easy we wouldn't have been summoned don't you think? Now get your ass off that rock and stop that mage!"

*Whoosh*

Think think think.

*Boom!*

"Shit!" That shit just sticks to everything! It is fucking magical napalm!

*Whoosh* *Boom!*

Wait! Of course! That's it!

*Whoosh* One, two, three,fou*Boom!*

"Still alive newbie? If you take much more time the vanguard will finish with the distraction and i don't think they will like what we are trying to do!"

"I'm on it!"

Five seconds between volley and four more to explode... Now!

I pick up a rock and get off cover and stand in the open, advancing like a fool.

"Hey! I'm heeere!" Aaaand...

*Whoosh* If this doesn't work that's gonna hurt...

*Swoosh* *Plop* *Boom!*

"Hyyyaaaaaagg!!!"

"Ha! That worked!"

"Damn, newbie! Didn't think you could pull that off. Alright guys, make sure that one's dead, shouldn't be too difficult after a direct hit from his own spell, those things are nasty and burn like mad."

"It's done, serge! Burned half'is head off, bashed the other half in."

"A'ight boys, contract's done so let's get the hell outta here."

"Well done newbie, but i have to say, not many have that accuracy throwing random objects like that rock, nor the timing to intercept the spell and send it back, on the other hand, why haven't you bought any weapon? I can't see that poncho being so expensive."

"To be honest i don't know how to use almost anything you have for sale, it's all medieval-like weapons and such, most advanced i've seen was a crossbow so..."

"Right, you probably come from a technologically advanced world. Well, you see, with a quasi-infinite number of realities there is not much that all of them have in common, souls is one thing, and the system is another, and that is basically all, if you bring something from one world to another, the most probable thing that can happen is that it can't even exist there and it just destabilizes reality, and even if it doesn't just explode in your face it sure as hell isn't going to work as intended, but you know what works everywhere, every time?"

"What?"

"Stabbing them in the eye, and bashing their heads in. That works, and we stick to that."

"Wait but, if we can't bring things from one reality to another, why can we bring these weapons? Hell, why can we go ourselves? We are not exactly from that reality."

"No, we aren't. But here, we are just souls given shape, and our own soul power keeps us stabilized, that's why we can recover from almost anything, why we don't need to sleep, or eat or get tired while we are here. And when we go somewhere we adopt a body according to local laws and our soul power is usually not enough to maintain us, so we sleep, eat, heal slower, etcetera..."

"That still doesn't explain how we bring our things, they don't have souls... do they?"

"No, but hell is not like the other realities, it was made to be a staging ground for hellspawn so every time we are summoned the summoner has to offer something to hell, diluted soul power, usually called mana, and objects, which are then turned into soulstuff that we can then use to build and craft things, and those things can be brought to other realities using our soul power and used there, but that only works for things that don't have to change, like a sword, or a poncho, we can't make explosives or acids because we can't know how they will react to wherever we go, the most we can do is make things that affect the souls of system races, but those things are costly, and usually one-time use, and need a shit ton of power to bring and keep stable so..."

"...So we keep to bashing heads?"

"You got it, newbie."
