Is there a more indepth description of constitution and what it effects? Does it effect health, resists etc.? When you cursor over where it says constitution bonus all it says is “The percentage bonus for your maximum constitution”.
constitution effects health. the more % to constitution you have the better, although its not necessary. what it does is, if you take damage then stop taking damage for a few seconds, you will lose constitution but you will regain health.
Basically its used to regen health while kiting or after battle, that way you dont always need to use your pots.
hope that helps 
Thank you.
you’re welcome
With 0% Constitution Bonus you can regenerate 3x to full health before you have to refill it with consumables that drop
