This is the only easy way to do that. Empire is the exception for Ethos changes.

As others have said, Welcome.

As far as cabals Scion is the most suited for the build you've described but I believe the Cult of Scarab could also be done. You could even pick a Herald although that would be the most unlikely choice I've ever seen aside from giving up spells and going Battle.

People are correct when they state it isn't a build for most people new to muds but if your used to getting hunted often then you should be fine. Once you learn a little from game mechanics, maps, and which skills do what, you should be fine.

As far as the Scion cabal. Up until last year I had never attempted it because I was told the same as you and my first try I was inducted. I may not be the weakest player around but had no prior knowledge of the cabal workings and with enough effort it wasn't too bad to get a place.

I will wish you good luck in whichever choice you make and again Welcome.
