When this modifier present, all alignments are randomized. However, there are several exceptions:
-Neutral Special roles will have their OG alignment, except for CS.
-Vampire converts based on role, not alignment. So if you try to convert Town VM - he will die, but if you try to convert Apoc Tracker - he will be converted.
-Non-NE roles with NE alignment won't have NE defense rule, while OG NE roles with different alignment still have that rule.
-CS aligned roles cannot spawn without CS in play (and their number must be same with amount of CS in game - so if 3 people start as CS aligned, then there must be 3 Cursed Souls with different alignments)
-OG wincons are disabled in favor of new alignment wincon.
-There must be at least 5 Town aligned players at the start of the game.
-Jackal is banned with this modifier
-This modifier cannot be enabled with Town Traitor modifier, but can be enabled with Egotist Townie
-There can't be more than 4 Coven-aligned players and more then 4 Apoc-aligned players.
-Necronomicon is given to Coven-aligned players first; however, if no one from Coven-aligned players have Coven roles, then the book goes to the random player with Coven role until his death.
-Necro Passing is disabled.
Note: if there is something I overlooked in terms of "weird" interactions that can be pretty much game-breaking - well, I'm not omnipotent, but I'll add this into details.
