Strength potions

I kinda find strength potions useless if it only gives +3 additional points in Strength. Same with HP potion. Buff?

Well Strength Potions Just Make You Do 3 Extra Damage. And Then For Crits You Do 6 More Damage On Average.
Obviously, Vitality Potions Give You 30 Health Straight Up. This Will Then Increase HP Regen, So They Have Their Uses.
