Need some help for an homebrew game.

[Zellsantal]

A friend of mine will be hosting a game soon. He calls it "Everyone is going to hell", the idea of this game is that the gate of hell opens up in our world and would be up to us to get into hell and either save the world or help bring hell onto the world. My friend have also said that anything goes which also means homebrew characters but try to make it some what balance. We would be level 15 to start out, level adjustment would not count and start out with any magical items one would want. There is me and three other people and two already have half of theres done, I can't remeber what they call can do but here is what I know.

One of them have a kinder artificer that could some how steal anything you have no matter what, and the second one is playing what is called Biofighter which is about the same as the Guyver anime. The biofighter guy with no magical items hehave "Vow Of Poverty" and I think "Monster of Legend template added to it. The Biofighter have like 40 STR and Dex, INT 18 and I cant remeber the other stats but his AC is 60. So I am trying to figure out how to match it or come close in some way.

Being in the setting of the game we would be playing I have thought for the hell of it come up with a half angel and half demon very much like Dante in the newer Devil May Cry game. My friend who is DMing this game said I could do it if I come up with a good story for it. The story part I believe I can come up with something good. However I am not sure if there is in fact a race or template that could do that.

So I ask if there is in fact any way I can make the character I am thinking of or if anyone have some suggestions I would be willing to listen.

Half Celestial (http://www.d20srd.org/srd/monsters/halfCelestial.htm) and Half Fiend (http://www.d20srd.org/srd/monsters/halfFiend.htm) are templates that can be added to any non-evil, non-good character. You are talking a total LA of +8 however, so if LA buyoff is not an option then you might want to keep looking.

Hell, even if it is a thing, look elsewhere. To buy off even one point of that requires 24 class levels.

So basically we can play How many templates can we legally stack ? here ?

That I'm not sure I would have to ask my friend, otherwise I might have to homebrew the race. If it comes to that how would I able to do that or is it all on the DMG?

If you can do infinite template stacking, get spellwarped for the last one, you become an aberration and get probably the highest non-divine spell resistance, and it actually scales better than a god's SR.
