Player Health

Much like Pokémon Legends: Arceus, in this game the player character can get damaged by attacks, both from wild Pokémon and even your own if you walk into the area of effect for your own attacks..

When you receive damage, you will start getting a black border around gameplay. When it turns red, you are in a critical state and will black out soon. You have a set amount of health, but that can be increased if you have obtained the Green Canari Plush.

When you're not being targeted down by an opposing Pokémon, you will recover 20 Health a second

If you lose all of your health, you will get taken to the last Pokémon Center you visited, or if it's a Rogue Mega Evolution battle, you will have to start again.

Damage

Unlike Legends: Arceus, however, the only way in this game to receive damage is through Pokémon attacks as your Rotom Phone will grab you if you're about to fall from a height. Special effects of moves including burn and poison don't affect you either.

The damage is determined based upon two factors. The first is on the Base Power of the move the Pokémon is using; the higher the base power, the more damage. Rogue Mega Evolved Pokémon's special attacks also in general do increased damage.

The second factor comes in terms of the total power of a Pokémon factoring in Base Stats and more creating a multiplier from 0.5 up to 1.5

After you have received damage, you will have a short period where you won't receive any further damage.
