Channeling is the ability to draw power from natural and celestial events. Witches are also able to channel the power from other witches. But in that case, a witch who wants to cast a spell must have some object from that other witch/warlock. Using too much energy from the elements (water, earth, air, fire) can kill a witch. It is first seen in The Sacrifice. Witches can channel powers of more witches at once as witnessed in Know Thy Enemy when Bonnie Bennett used the powers of 100 dead witches.

Note: Almost all witches in the seris have used this form of witchcraft by simply drawing from the elements or cosmic events. The below instance is just a notable instance.
Bonnie Bennett and Luka Martin
Luka taught Bonnie to do this. She gave him her necklace, and he gave her his bracelet. Those objects work like talismans. They have lifted a lot of leaves using each other's energy. After that Jeremy came, so Luka forgot his bracelet. Later in the episode Bonnie used her own power plus his power by channeling to open the tomb to save Jeremy who's in it. At the same time Luka felt weaker and he fell on the floor. After some time she got a nose bleed and she was unable to continue. In The Last Dance, Bonnie channeled the powers of 100 dead witches to kill Klaus, but she used all of her energy so it killed her, although it was temporary cause she cast the spell before to fake her death.
- Fear: As with all witch powers, if a witch if deeply afraid of something their powers will be weaker, and until they conquer their fear, their powers will remain blocked.
- Awakening: If the user goes into a trance, breaking them from it will usually lower the intensity of the flames and will definitely stop the caster from igniting more.
- Overuse of power: If a witch uses too much power, it will kill him/her.
