My question is: Does energy leech only regenerate adrenaline when you are not using an artifact? I checked the wiki for the answer but it simply stated energy leech's effect is: "Whenever you damage another monster/player, you gain 1% of the damage as adrenaline. Each level increases this by 1%. (Max Level: 5)"
Also, a side question is how much extra damage does a weapon do for each +1?
Thanks!
