I'd like to suggest the following things in the future:

1. Enemies with infinite defense (such as Metal Slimes from Dragon Quest) - Players would only be able to inflict 1 point of damage to them regardless of how powerful their attacks are. To balance this out, these enemies would typically have low HP (like 10-20 HP).

2. Petrification Status Ailment (and enemies that inflict it, like a Cockatrice, or a Gorgon) - For a couple seconds, the affected player (or NPC) is unable to move at all, leaving them vulnerable to more attacks. However, to balance this out, the petrification counter cannot be resetted while petrified, so no situations will arise where the player can be left petrified indefinitely until they died. (Another possible side-effect is that, while petrified, the subject's defense is increased.)

3. An accessory that prevents status ailments (except for potion sickness) from affecting the player (such as the Ribbon from Final Fantasy games).

4. Vampiric Regeneration - Certain weapons and NPC attacks steal life from their victims and use it to heal their users.

5. Receiving damage from the environment itself - For example, say that you enter the Underworld or an Arctic Biome, if you don't have a certain accessory equipped (like, say, a Ring of Heat Resistance for the Underworld, or a Ring of Cold Resistance for the Arctic Biome), then you'll slowly lose life from the extreme heat of the Underworld, or the extreme cold of the Arctic Biome. This damage is separate from damage from touching hot terrain (like touching Hellstone while not wearing an Obsidian Skull).
