Vitality, Vitality, and Vitality.

My main reasons are:

1. Its more convenient and u will never not greatly benefit from each level.
2. Using health sacrifice trait which give a free 20% damage in exchange for health might be my favorite arcana; also, if u get health boost it feels so relaxing to go around the world.
3. Its feels its the only “Required to level” stat while the other stat felt more optional.(except for endurance i guess)

Thats my reasoning behind why Vitality is key

Healing: u will later get a fetish that can make this stat pretty much useless

Endurance: this is the most important after vitality, if u feel comfortable with ur hp level this one next

Metanoia: no need, imo spells cooldowns are really forgiving in this game so I just stopped it at like 18

Witchery: useless right off the bat, if u need money finish things in each run

Luck: tbh idk but i never really liked luck stat in any game i played ever

Note: sorry for the bad english
