Luminary PC game developer Blizzard has revealed some information regarding the health system that will be used in Diablo III.
Just like in the previous games, your hero’s health will be indicated by a red orb at the bottom of the screen. As your health decreases, liquid drains from the orb. Health potions will of course be the staple diet of any wannabe dungeon crawler, but according to Blizzard, they will be “moderately rare and limited by cooldown: multiple potions can’t be used in rapid succession in the middle of a fight.”
“You might have a class skill that can help you regain health, but health-restoration skills are specialized, require careful play, and usually incur consequences.”
“Potions and skills offer excellent boosts to your health, but to survive multiple battles, you’ll need to use them alongside a more reliable, renewable means of recovery.”
“That’s where health globes — floating, crimson spheres that rise from the corpses of your defeated foes — come in. These globes are the core means of regenerating your health in Diablo III, and all other methods of healing support them. When you pick up a health globe, your health (and the health of any allies in your party) is restored by a fixed percentage depending on the type of globe you’ve grabbed.”
“Major boss fights make unique use of health globes. Each boss battle includes a custom-designed means of utilizing these globes to regain health. For example, in one fight, you might have to split your attention between weakening a dangerous boss and slaying its irritating but ultimately less-dangerous minions in order to get enough health globes to stay standing. In another fight, the boss itself might drop health globes when it takes damage, or you might have to hunt for hidden caches of globes in the midst of battle.”
