Invincibility

Invincibility is the ability to be totally resistant to all forms of harm. Because of this, the obvious problem with Invincibility is that it could very easily make a character who has the superpower overpowered. To counter this potential issue, Invincibility comes with many limits, with one being how incredibly rare it is. Invincibility is unlocked through any abilities, weapons, tools, or equips that make the user, holder, or wearer completely immune to incoming harm.

Limitations

 * The user has a very short time to be invincible.
 * The user has a long cooldown time.
 * The user is only invincible to certain attacks.
