Using Sentinel Crystals

You can find Sentinel Crystals through the levels in the game and they are marked on your map, once you find the automap. So you should start to unlock them passively, without putting in too much effort to find them (hopefully).

Once you find the Crystals, you will be taken to a screen where you can select the upgrade you want, split between the aforementioned three options. If you select armor or health, those stats will both increase by 25. If instead you select ammo, it will increase the cap for all types.
