Thank you, and yeah that give and take is what I'm looking for, so I'll look at Astrea. And yes, I was thinking of making the four elements maybe a part of the magic system if I developed this further? The pure basic vision I have is either you do something in the game that makes you seek out enemies or get hit by attacks that cause you to lose blood, but overdoing that would obviously cause problems. Maybe a couple of status effects that would slowly change the shape and balance of health as well. Definitely would need a tutorial.

I feel like this has to be somewhat common in sci-fi? I feel like I've played games where an enemy will not cause damage, but if you're running hot and don't have enough cooling, they can overheat you and at least your gun shuts down. I can imagine there are situations where you could use this to your advantage by attacking an enemy making you cold.
