Is it possible to make health potions that replenish your health completely or can they only be found/purchased? It takes tons of regular health potions to refill my health bar and my character doesn't use magic.

If you had the right Alchemy level, some Alchemy improving gear, and the right perks you could get pretty damn close. But it all depends. If you are at level 30 and all your upgrades went to health, probably not.

theres a potion you find at higher levels that will replenish your entire health in one hit. not sure about making them though.

Thanks. I can buy the potions it's just frustrating that I can't create them. I decided to grind my alchemy skill up to 100 and wasted several perks on the tree to still have to buy if I want good health potions.

Ultimate healing potions are everywhere once you are high level enough though.

This. But you'll rarely use it once you're level's high enough to take damage from enemies. I even have 66 Ultimate Healing Potions in my inventory and counting...

Yeah but after spending the time and perks I had hoped for some return other than gold from alchemy. I can make Wicked poisons and other potions but my character doesn't use them.

I take a lot of damage from high level mages since I use two handed. I'm working on finding some magic resistant heavy armor but am having poor luck so far.
