This is the 167th episode of the new tutorial series on Action RPG game using Gameplay Ability System. Here we are going to continue with the health upgrade skill we started implementing in the last episode as the first skill in our skill tree. Here we will add a MaxHealth attribute to the BaseActorAttributes and that will be used to control the max health character can have. Also as we upgrade the health level, the health bar length will be increased so player can visually see the upgrade.
