So here's my suggestion, as i notice in many game, to understand the possibilities of things you can do, abilities tree exist, to allow you to read "passive skill" for exemple second wind is technickly a passive skill, but beside discord or youtube vids there isn't anything much in game, that's why I think an abilities tree, with your passive skills in it would improve the gameplay, and understandng of the game is needed.
exemple :
(Set,icon)When you fly over ("set'amount'of'height") your stamina decrease faster.
