Witcher3

[Jaeger]

I maxed out Muscle Memory (fast attacks) and Strength Training (strong attackss) in the Combat Tree. I maxed Delusion (Axii skill) mainly for dialogue, although it's not bad for combat either. The vast majority of the points went into Alchemy. It's weak early on, but will pay off once you are able to craft your alchemy tools.

I greatly enjoyed the character build system in the original game. It was extremely flexible.
