Simple solution is “resistant damage” - damage taken by burning your life force to power spells can only be healed by natural healing, not magical healing. It’s tracked separately, and similar to subdual damage, you add it together with normal damage to determine if the character reaches 0HP. If you choose to go this route, I suggest that HP not be your primary fuel for spellcasting, but rather have the patron grant a class feature that allows “overcasting” by burning one’s life force to power additional spells after you’ve run out of normal spell slots.

Originally the machines were going to use human brains for processing, but apparently the explanation was deemed too technical, so they changed it to some mumbo jumbo about power, which also let them use the nickname Coppertop.

A partner of mine has an above-range microwave with the worst implementation of this that I’ve ever seen. When you mute the button beeps, it mutes the entire microwave. Food finished cooking? Silent. Manual timer set? Hope you’re looking to see when it hits zero. There’s no way to silence the buttons without muting all alerts completely.
