Manifest: Death
How do Manifestations die?
“Die” probably isn’t the best word for it. In Pokémon, the mons simply “faint.” You can’t permanently lose a Pokémon, and I doubt Manifestations are any more transient. They must be able to “demanifest,” however, else combats will last forever, and all the damage-dealing and condition-applying is so much nonsense.
So, how does a Manifestation demanifest?
The obvious answer is, as always, their HP reaches 0. That’s not a terrible metric — there are reasons why cliches stick around — and a lot of systems will naturally fit into it. While I may find a more interesting ludo-narrative later, this is a good place to start. Let’s play with some numbers.
