Why is there no flask to help Energy Shield defense?

ES is not a defense, it's a form of HP.


Armor and evasion are defenses, they reduce the damage you take. ES is a resource that takes the place of HP by being depleted when you recieve damage.


A potion doubling ES would be the same as potion doubling HP... incredibly overpowered. even more so because you can still have armor or evasion on top of that.


ES doesn't need in-combat regen potion because that's what makes it different than HP, that it regens quickly out of combat at the cost of not regenerating in-combat
