Augmentation

Augmentation is the magical ability to increase the powers and abilities of oneself or another. This is an extremely rare and powerful ability as it allows the user to makes their powers stronger and themselves more powerful.

Users can not steal or give powers, just enhance the powers the user or another already have.

This ability is also accessible through powers such as Empathy, Projection, Thought Projection, and Pathokinesis, or through spells and potions.

Projection


Billie Jenkins accessed this ability through her power of projection. She was able to project her desire for power into an actual power increase for Christy's Firestarting power. With Billie projected power increase for Christy, they were able to vanquish a demon thought impossible to be vanquished.

Empathy


Prue Halliwell displayed this ability after she temporarily gained the gift. She effectively had the entire rainbow of human emotion under her belt, and to extreme degrees. This exceedingly high inflow of emotion granted her a massive power boost, to the point where she became more powerful than the thought invincible demon, Vinceres.

Her Telekinesis power evolved to the degree where they significantly enhanced her agility and flexibility, allowing her to perform gravity-defying maneuvers and spectacular martial-arts feats. Her power of Astral Projection evolved into Cloning.

Tripling One's Power


Prue was once able to use this ability through a spell. She casted a spell to triple a witch's strength in hopes of multiplying her Telekinetic power.

Pearl Russell had only one known power, Pyrokinesis. However, she was able to triple her power through the use of a potion made by the warlock Anton. The potion made her stronger and advanced her power into Fire Throwing, which enabled her to fight off her cousin's Cryokinesis power.

The Evil Eye


The evil eye is an ancient Gypsy talisman that is blessed with the ability, augmentation. Lydia Nicolae owned the necklace and used it to augment her power of Optical Thermodynamics; the power to shoot green beams of energy at an opponent.

In early 2002, Phoebe was experiencing problem with her power, she hasn't had a premonition in several months and could barely levitate. However, as soon as she touches the tailsman, she gets her first time Astral Premonition.

Limbo


When someone enters Limbo, their abilities are temporarily advanced. Yen Lo discovered his power of levitation advanced to flight allowing him to fly up to the clouds and use them as a portal out of Limbo. An Ling and Phoebe discovered similar advancements which they used to fly Piper, Paige, and themselves out of Limbo. Paige's powers also advanced and she didn't have to call for an object to orb it. For instance, when she thought of orbing the Dragon Blade to her it happened before she could say it's name. She was also able to orb Piper's soul out of the Dragon Blade. A feat which she probably wouldn't be able to achieve under normal circumstances.
