An odd thought occurred to me out of the blue: The fluff text for Effortless (Yozi) Dominance explains that releasing more of your motes into the environment twists the universe to cooperate with your efforts (resulting in cheaper Excellency activations). Would this reasoning mean that, inside their world-bodies, the Yozis have maxed-out discounts on their excellencies at all times? They are suffused with their own essence, after all.
It's an intellectual point since the number of motes a Yozi would have to spend to otherwise max the discount is negligible compared to their total pools, but I'm curious about what the community thinks.
Edit: And it could probably be relevant if an Infernal were to be fighting inside an area already tainted with their essence, such as a personal manse.
Huh, that makes sense, and would mean setting up (YOZI)-aspect manses would let you (an Infernal) gets discounts on the like-(YOZI) Excellency, which... You look even more like a final boss for a game (well more like Dungeon), which actually would be a really fun playstyle.
You do your empire building, and you have as your headquarters, a submerged Kimbery-Aspected manse in the middle of a Lake (Water Temple)[1]. The Plucky Young Hero's come fighting through, and when they reach your throne room/hearth-room, you begin the
boss fight, you get a discount on your Kimbery-Excellency, and since its underwater, they have to have environmental survival charms, or they are trying to drain the lake to destroy the manse.
On the other hand, if you are the Plucky Young Hero, then your BBEG has a unfair auto discount on his scene long IAM equivalent, and you are at a disadvantage mote-wise, but you are walking onto a prepared killing ground anyways, hmm.
I would use that, because it feels thematic, and it provides plot hooks for everyone.
If Infernal, do you taint the Manse toward a (YOZI) or not. Is it worth the advantage that the Yozi essence would give you, and that might be noticed by your enemies? Or, the Hearthstones, do you risk having a potential fuel source knocked out of commission, or do you keep the normal aspect for the hearthstone fuel.
If not Infernal, if the Infernal has tainted the (de)manse, once you kill the Infernal (if attempting to kill), do you leave the manse standing, do you twist it back to a normal manse? Do you level the Manse and transform the Demanse to one of Creations elements?
[1] Does not have to be Kimbery-Aspected manse, that was what came to mind.
