Invincibility

Invincibility is the ability to withstand any amount of physical damage or harmful force of any kind, causing no harm or pain to the individual gifted with this power. Beings with this ability tend to be immune to most forms of magic, including powers, spells and potions.

Although invincible beings cannot be hurt under normal circumstances, if they are somehow weakened, it is possible to kill them. Additionally, they may not be immune to having their powers stripped.

 * Yama
 * The Tribunal
 * Angel of Death
 * Angels of Destiny
 * The Cleaners

Taking In The Hollow
The Hollow can grant invincibility to whomever possesses it or whomever it possesses. However, there is a price for this form of invincibility, if a demon or witch is possessed by the Hollow, they will only be able to control it for a short time after which they fall victim to its insatiable hunger for more power, thus doing what ever it takes to attain more power and in return, eventually destroy the world.

Drinking From The Eternal Spring
Whomever drinks water from the Eternal Spring will become invincible. These beings can not be killed or vanquished with an active power, but can be still be affected by spells. The only known being to drink from the spring is the demon Tull. He was later transformed into a tree by Piper and Paige.

Cast A Spell To Turn Someone Invincible
Paige once cast a spell to grant Darryl invincibility during a hostage crisis. On top of making him bullet-proof, he also gained overwhelming physical strength, over which he had little to no control, causing him to unintentionally destroy things with minimal effort. She reversed the spell a few hours later at his request.

Wielding Excalibur
The true, destined wielder of the sword Excalibur gain Invincibility. However, those who wield the sword without being its true master will be corrupted by its power.

Wielding Hadhafang
The true, destined wielder of the sword Hadhafang gain Invincibility. However, those who wield the sword without being its true master will be corrupted by its power.

Gadreel's Athame's
Gadreel's Athame's are a set of athames that are infused with Gadreel's blood. He instructed a group of demons to create these athames for him. He then gave them to those demons and presumably others. The demons used them as weapons against the witches and their other enemies.The Athames allow the demons to avoid being vanquished by even the strongest of powers. It also grants them with numerous other powers, although all of them are currently unknown.

Absorbing Powers
Cole Turner inadvertently discovered that he had returned from demonic wasteland invincible due to the massive amount of powers he had absorbed after numerous failed attempts to take his own life in 2002. However, he was not immune to the Power Stripping Potion, as shown when Paige once stripped his powers.

Consolidating Power
By consolidating powers the Avatars eventually became invincible. This is made evident by the fact that Leo became invincible when he chose to become an Avatar. The Avatars can only be killed with special potions.

Experimentation
Pator and Rondok were a pair of brothers who were experimented on by other demons to make them un-vanquishable. However, the Jenkins sisters proved that the brothers could be vanquished when they consolidated their powers and successfully vanquished Pator in 2006. Rondok, however, was banished to the Astral Plane by two magic school students, Ryan and Jen.

Releasing Repression
A method unique to Lord Dyson and his kind. Through their power of Releasing Repression, they can release the suppressed anger of people, feed on it and become more powerful. If they absorbs enough anger, they can become invincible. The downside to this method is that if they absorb to much anger, they will overdose and explode.
