One of the things you must do in the game is frequently resting and regenerating the main statistics of the character. These statistics enable you to fight, perform all effort throws in the game etc. Because of that, you must regularly replenish the pool so that you successfully progress through the game. There are two main methods of regenerating your stats:
You must rest and allow your party to regain their strength. Usually each larger location has a few places where you can rest. In Sagus Cliffs such place are Tranquility's Rest or the camp of the Disciples of the Changing God. By resting you will regenerate stat points of your whole team. Additionally, you will obtain a positive fettle Rested, which provides you with +5% critical success chance for any action. Usually resting isn't free, so make sure you have shins.
You can use items and ciphers that regenerate selected stat pools. It is a fast way, perfect when you are far from a potential resting place. You can also use such items during battles, but you should keep them for dangerous situations.
Remember to regularly rest and regenerate stat pools. It is especially important when you start a new quest or after you've had a few fights. Additionally, make sure you have some reserves of items that will quickly regenerate your might, speed or intellect when you need it.
