So guys, i am trying to make a mini-campaign. it involves our group psyker having an inner battle against a daemon. if he wins his battle, then he binds the daemon and our group will have a new powerhouse. if he fails. well.... bad things will happen. i really think this could make for some interesting adventuring. the only problem, is that i need two characters. one is of course the psyker and the other would be the daemon. i need the two of the to be, for the most part to be equal in power. my other thought is to give someone in the group, who is a psyker, (and i know someone will make one) the option to become the daemonhost.

i just need any thoughts, and i also needed to know if anyone had or knew a place where i can get basic premade characters. (the psyker, and daemon) any and all thoughts and help, would be much appreciated.

I think I need a little clarification on this...

Are you trying to have the struggle against the Daemon ongoing during a regular campaign? Or is this completely separate where the fight against the Daemon is a small campaign in itself?

As with either one, the player who will be playing the psycher, shouldn't he be making his own character?
And as far as the Daemon goes I would custom tailor it to whatever the Psycher was, trying to make the proverbial contradiction, the perfect spear verses the perfect shield. This way the player really has to think outside of the box to defeat the Daemon, both with a strength of will and toughness.

And if you are running the struggle during a regular campaign I would have the Daemon as a more insubstantial threat. Something that tempts him, uses him, gives him power and tries to enter the material world through him. The hardest part will be to keep this information separate from the other players so that they don't know that the psycher is possibly about to loose his soul to a daemon.

I think the best way to actually do this is to give him (the psycher) increasingly hard challenges, both will based and even toughness based, everything from riddles in dreams to fighting phantoms alone in an alleyway. And give him access to increasingly more power, but make the cost of that power higher and higher till he really has the chose of loosing his soul, or to completely defeat the Daemon.

I hope that was helpful.

So, the Psyker is a PC? I don't know about your players, but I wouldn't enjoy playing in a campaign that revolves entirely around another player's PC, with the rest of the party reduced to the status of "supporting cast"...

The OP states that it is a "mini-campaign" for their existing characters. I read this to be more that the poor psyker was a tad neglected or marginalized in the main campaign so the GM is trying to cook up something a little spicy (and grim) for the player. Think of it more like a mid-scene cut like the classic Star Wars movies did.

I would very carefully hand-craft the daemon to mesh well with the psyker character's abilities or this can end very badly. Four of the characters in my game are psykers (one primaris/templar, one primaris/scholar, one adept/sage, one xenos) and each of them have VASTLY different strengths and weaknesses, so what threatens one is hardly a nuisance for another (and vice-versa).

If you own a copy of Daemonhunter, flip to the "make your own daemons" section and make sure to select options instead of rolling in a few key spots to ensure that you have a unique (or at least distinctive) daemon that can hold it's own against the psyker when solo.
