if u take the evil path of one tear......it should be granting +2 AC....but i still get +10 magic resistance.....

im playing solo.....must the sarcrifice be one of youre party members?

Never tought about that, good question... but whatever will happen, your alignment will always change to evil.

I must say this, my alignment remained true neutral whatever I did. A bug maybe?

You might get away with it, if you are a druid or paladin, where there is only one alignment. My kensai/mage only drop to neutral evil, the lowest you can get with kensai.

I was mc fighter/mage/thief so alignment doesn't matter.

im not sure, but i think u always drop to neutral evil. my paladin did, stalker did, LN assassin did, and so did my fighter/mage no matter how many evil paths i took.
