When you start out in Star Wars Jedi: Survivor, you will have a minimal amount of Force at your disposal. In combat, you will only be able to use the Force a total of four times before you will need to recharge it. This is indicated by the blue bar at the bottom of the screen, below the white stamina bar. When you are exploring and not in combat, you can use the Force as much as you would like.
However, if you want to use the Force during combat, you might be interested in increasing your maximum amount in Star Wars Jedi: Survivor.
There are two different ways that I have found to increase your maximum Force. Both of these methods will give you more charges of Force before it needs to recharge. To see those methods and permanently increase your max Force in Star Wars Jedi: Survivor, keep reading the guide below.
Increasing your maximum Force in Star Wars Jedi: Survivor
You are luckily able to increase your max Force during the first hour or so. By visiting the Skills menu through a Meditation Point, you can view the Force section. Here, one of the first Skills you can unlock is called Attunement, and this will increase your maximum Force, plain and simple. Other Skills in the section also accomplish this same goal, but they require more skill unlocks to reach.
The second method of increasing your maximum Force is by looting Force Essence. These are lootable items that are scattered across the different levels of Star Wars Jedi: Survivor. I was able to find my first Force Essence on Coruscant by going into a small room away from the main story route. When you loot a Force Essence, your maximum Force will be increased. Force Essence is found as a glowing purple crystal on the ground.
Aside from those methods, I was not able to discover any other ways of increasing Cal’s maximum Force.
