In your travels, Geralt will gain ability points (both by leveling up, and discovering Places of Power for the first time). You will be able to spend these ability points on Character Abilities, which can be customized and improved to customize your ideal Witcher.

First you will have to unlock a desired skill from one of the four trees: Combat, Signs, Alchemy, or General. Once you have unlocked a skill, you will then need to apply it on the diagram on the right. You will only have so many slots open to you (A total of 12 ability slots and 4 mutagen slots) which means that you will either need to be very careful about how you build Geralt, or remember to swap out skills to properly meet each challenge you face.

In addition to the ability slots, you will be able to apply up to 4 mutagen slots to further enhance your abilities. Mutagens are gained from killing monsters, and their color not only corresponds with three of the ability trees, but will also further enhance any of your abilities of the same color placed near the mutagen. For example, placing a blue mutagen in the top left slot along with any other blue abilities will increase their intensity, with more intensity for every blue ability on the top left slots.

the gold general abilities do not have a corresponding mutagen, but are varied in their passive bonuses - so mix and match wisely!
