The Outlast Trials features a plethora of perks and upgrades that players can purchase as they make their way through the game, giving their character all sorts of useful abilities to help them through their Trials. Players can find some of these perks in the Pharmacy, where Emily Barlow will sell them Prescriptions. The Pharmacy will become available to players once they hit Level 3. At this point, players will only be able to access the Tier 1 Prescriptions. Once they have bought every available perk in Tier 1, players will unlock the more powerful Tier 2 perks.

The Outlast Trials can be incredibly difficult, and players will want to make sure their hard-earned money is going towards the best upgrades they can buy. With so many available, players may not know which perks to prioritize and buy first, but luckily, they can find some of the best Prescriptions in The Outlast Trials here.

10 Instant Use - Tier 1

The Outlast Trials Instant Use

The Instant Use Prescription is available for players as soon as they unlock the Pharmacy. It allows players to unlock the ability to interact with an object instantly, instead of having to add it to their inventory first for use.

This perk shines in situations where the player finds themselves with a tight inventory. Instead of having to forfeit some of their items to pick up a heal, players can use this ability to heal with objects they find as they make their way around the Trial.

9 Slide - Tier 1

The Outlast Trials Slide

For gamers who have played the original Outlast, the Slide Prescription may seem familiar. Unlocking this perk will allow players to slide if they press the crouch button whilst sprinting. Not only is this ability incredibly fun, but it's also great for helping players out of a bad situation. Players can use this perk to slide out of the way of an enemy and evade their attacks.

This is a great perk for players to pick up early on, as it will greatly improve their survivability. Once they have it, they'll wonder why they didn't buy it sooner.

8 Regeneration - Tier 1

The Outlast Trials Regeneration

Players unlocking the Regeneration Prescription will find their survivability increased by quite a lot. This handy perk will result in a small amount of health regenerating after a short delay. This perk in particular is handy for newer players to pick up, as extra health is always going to be helpful, and can be the difference between winning and losing a Trial.

The Regeneration perk also saves the player some inventory slots, as they can focus on picking up more offensive items instead of healing.

7 Run and Smash Doors - Tier 1

The Outlast Trials Run And Smash Doors

The Run and Smash Doors Prescription is probably one of the first perks players will find themselves picking up, and for good reason. This Prescription allows players to instantly open doors whilst they are running, as well as being able to crack locked doors.

Players will find that this perk is incredibly helpful when they're being pursued, as it gives them a few extra seconds to escape their enemies. One of the most frustrating things players will find they have to do in a chase is stopping to open a door, giving their pursuer time to catch up with them. Luckily, this Prescription stops just that, making it great to have around.

6 Speed Boost - Tier 2

The Outlast Trials Speed Boost

The Speed Boost Prescription does exactly as its name implies, and gives players an increased running speed. Though the speed boost could be a little faster, there is truly no downside to being able to move around the Trials at a quicker pace. The speed boost allows players to make more ground on their pursuing enemies, potentially saving them from taking a hit, or worse, being killed.

It also allows players to traverse their objectives faster, allowing them to beat their enemies to the location. The Speed Boost Prescription is just nice to have for players making their way around the Trials and is overall a decent perk to have.

5 Heavy Training - Tier 2

The Outlast Trials Heavy Training

The Heavy Training Prescription, first made available for players at Tier 2 in the Pharmacy, allows players to move faster when they are carrying large objects. This perk is really helpful as players are often at their most vulnerable when they are carrying large objects around.

Being able to do this quicker reduces the time they spend in a state of vulnerability, and is overall just a really handy Prescription to have. It's especially for certain objectives, such as carrying fuel to start up a generator.

4 Expanded Inventory - Tier 2

The Outlast Trials Expanded Inventory

Players who unlock the Expanded Inventory Prescription will have access to four extra inventory slots during their time in the Trials. This means they'll have plenty more space to gather more stuff to throw and additional health packs.

Using this Prescription can also give players a bit more flexibility with their builds. For example, players can use some of the more experimental Rigs as they'll have some extra space for items to use as a backup.

3 Endurance - Tier 2

The Outlast Trials Endurance

The Endurance Prescription reduces the player's stamina consumption when running. No matter how stealthy players think they are, at some point or another, they're bound to bump into one of The Outlast Trials' terrifying enemies. It's at this point players will be grateful they grabbed the Endurance Prescription, giving them an extra few precious seconds to gain some ground on their pursuers, and hopefully make their grand escape.

Some players might just prefer running around their Trials anyway, without being too concerned about bothering enemies, and the extra stamina lets them go on for a little bit longer. Whichever play style players prefer, the Endurance perk is always handy.

2 Athlete - Tier 2

The Outlast Trials Athlete

Athlete is an overall decent Prescription to have, and can be unlocked once players reach Tier 2. This perk will increase the player's maximum stamina. The Athlete Prescription is handy because stamina affects most things in The Outlast Trials, such as bashing, running, jumping, and climbing.

As a result, this perk is incredibly helpful for players to have. Having that extra bit more stamina could save a player from being caught by an enemy.

1 Doors Basher - Tier 2

The Outlast Trials Doors Basher

The Doors Basher Prescription is an absolute must, and players will be able to unlock it once they hit Tier 2 in the Pharmacy. This ability allows players to break through locked doors in just two hits, which can easily save a player in an intense chase.

The quicker the player can take down a door, the quicker they can get away from their pursuer. It's a win-win. It's especially helpful for solo players, who can't rely on their teammates to help make a path for them.

The Outlast Trials is available in Early Access on PC.
