The Binding Spell is a spell that can be used two entwine multiple items together. It can be for individuals, or for elemental powers.
"Elements that knit and bind. Hear my will, join different kinds." - The version used to steal the Nowhere Boys' powers and give them to Phoebe, as well as returning them to their proper owners later on.
Alice Hartley uses it to bind her and Oscar Ferne together. She approaches him under the guise that she could let him walk again, but in reality it was a trick to control him, so he would steal the talisman from Felix. The spell requires a lock of hair from both Alice and Oscar to take effect. It allowed Oscar to use his legs again, as well as run at superhuman speeds. Alice also gains full power over his actions, while Oscar remains aware but is no longer in control over his body.
