While you can get higher health by equipping armor and accessories inCore Keeper, it’s not permanent. That health only lasts as long as you have that armor or accessory equipped – and if it’s armor, it has to have durability left. If you want more health permanently, you’ll have to find some special consumables.
These consumables are filled with a strange power, and there’s no way for you to grow them like normal crops, and lesser enemies won’t drop them. If you want to be as strong as possible, you’ll have to scour the underground for where they hide, from the blazing desert to the dangerous jungles.

How To Permanently Increase Your Max Health
There are a total ofnine special food itemsthat, when consumed,permanently boost your Max Healthby a specific amount, regardless of when they’re obtained and used.
You canonly obtain the Max Health buff once per consumable, but anyduplicates can still be eatenfor theirfood bonus or cooked into different dishesin a Cooking Pot.

In some cases, the item alsoprovides some extra buffsas well, such as theAnniversary Cakegiving abonus to your Glow stat, making themhandy to have aroundeven if you’ve already gotten the Max Health from them.
You can tell whether you’ve obtained a consumable’s Max Health buff by checking their description. If theMax Health and only eaten once text is green, you haven’t eaten it. If you have, the text will be grayed out instead.
