I've died countless times in this game at adept level. The health regen is fine as is for me.

Any progress on this yet? Or will this require the Creation Kit?

I don't know, I do pretty well using ironskin and wards. I really enjoy wards, actually. My mage rarely if ever has to use a health potion. I often just sell them for extra gold.

Got this after browsing the nexus for a few minutes:
"There are already console command to disable health regeneration. But it works only until the game is restarted. To disable this regeneration permanently you should use .modav instead of .setav. But .modav cammand works a bit differently. You also should use a negative value there.

So this is what you need to type in the console:
player.modav healrate -0.7

Just save after this and say goodbye to regeneration. "

Yea same here. I doubt after getting hit by a giant during battle, you're gonna say "well I'll just wait since it regens so fast"

Thanks, but I'm looking to keep health regeneration functionality from food and potions while also turning off "inborn" health regeneration.
