- Jerkass Woobie: Atlanteans in Late Age, possible Asshole Victim and He Who Fights Monsters. We will not ask what happened to the Caelian smiths who were kidnapped and forced to teach ice smithing, but seeing they aren't around... Are those your relatives restarting the horrid blood rites of Mictlan overseas?
- Laser-Guided Karma: The Kindly Ones. Three horrific entities from Greek Mythology hunt down (e.g duel alone at night) everyone who remotely harmed an innocent virgin for her blood. Every month. Until they are all dead. Any blood-heavy rival is going to lose blood mages at an incredible rate every turn.
- Moral Event Horizon: Casting Burden of Time. In-Universe it's perhaps the most vile spell that is available to players. Out of universe, setting it off during a multi-player game is a sure-fire way to get everybody (aside from the AI) to gang up on you. Considering that it quickly ages the whole world, increases unrest and about 2% of world population dies every month because of this spell, it's hard to argue with this reaction.
- A lot of (if not all of them) Blood Magic spells count as well, mixed with jet-grade Nightmare Fuel. Sacrificing an innocent girl for the smallest effect in the first place (which aren't always clean, some of them involve tying them to feast tables and let them be devoured alive by demons, skinning them alive, boiling them in cauldrons), later rituals make the caster sacrifice hundreds of girls in a beastly ritual and summoning incredibly evil demons who will seduce, rape, bribe and murder people for fun.
- Motive Decay: Hits over half of the planet as time goes by. Even in multiplayer games irrelevant of the plot, blood magic will be an inevitable source, it is senseless not to use it unless your factions autokills local population like Ermor.
- The Extremist Was Right: Played Straight with Ulm. The spellcasting elite of The Empire form an ancient conspiracy to topple empires. The Iron Faith may have killed some innocents, but it also has saved the Empire during The Malediction which made the air turn From Bad to Worse.
YMMV / Dominions
