If you level up proabably leveling 12 Endurance is the best. It allows the player to do 4 Attacks(more than that is a garantiet hit) and 2 Rolls with the stamina more is not needed.
Great Game, but kind of easy Bosses and vigor is kind of pointless because the bosses are not oneshoting you and the flask are the same strength.
The Sekeleton has a over hat slam that can be looped over and over to allow for easy attacking.
The Second one is just roll or strave and then hit him 4 times R1 and roll away.
Overall great
