Horizon Forbidden West

Another trophy you’ll naturally get as you play, because Forbidden West throws skill points at you like they’re going out of fashion. In fact, by the time you hit the end-game, you’ll likely have maxed out 4 or 5 Skill Trees! 

But, if by some miracle you haven’t, head into your closest completed one and max it out the next time you get skill points. It’s probably best to focus from the off anyway - I personally stuck everything into Hunter, as I loves me some bow combat! And remember, you need to max out the Valor Surges too to max out a skill tree. Regardless, it tells you how many skills you have locked and need to unlock as a counter on the skills page itself.
