The Roots update in PEAK introduces one of the unique consumables in the game so far: Fortified Milk. One would question why they’d ever need milk in a climbing game, but this creamy power-up can make all the difference in a deadly encounter. Fortified Milk is a Roots-specific consumable item that’s capable of shielding you from harm when things get rough. You’ll start with one at the crash site and probably wonder how and when you should use it in PEAK.

Want to unlock every achievement in PEAK? To help you out, here's how to get every trophy available in the game.

What Does Fortified Milk Do in PEAK?

In PEAK, Fortified Milk is a consumable that gives you temporary armor. When you drink it, a shield forms around your character. This barrier blocks attacks and protects you from environmental harm. It doesn’t matter if you’re hit by a spider or caught in a harsh wind, the armor keeps your stamina bar safe and prevents it from draining.

However, the effect disappears after a few seconds. As such, you should only use Fortified Milk when you need it the most. It’s one of the most useful items in the game, but timing matters.

Using Fortified Milk also ties into a new in-game achievement called the Calcium Intake badge. You’ll unlock this badge after blocking 100 total damage with Fortified Milk. It’s a nice reward for players who know when to use it wisely rather than wasting it on minor skirmishes.

You might find your first bottle of Fortified Milk right at the crash site. After that, though, finding more bottles becomes a mix of luck and exploration. The milk appears mostly inside luggage scattered across the map, so looting everything you come across is non-negotiable. Explore as much as you can and grab every bottle you find.

It’s advisable to have at least one Fortified Milk in your inventory at all times while you’re exploring the Roots biome. This is because Fortified Milk’s shield effect can give you the edge during high-stress moments, especially when facing aggressive enemies or environmental hazards that threaten your stamina.

Fortified Milk might be more common while the Root biome is active in the game’s rotation. Once the event ends on November 17, the map will only appear occasionally. This means you might not be able to find Fortified Milk as easily once the event ends. So, if you’re planning a long climb or aiming for the Calcium Intake badge, now’s the time to stock up.
