Lilia uses magic during his Master Chef course to instantly grow pea shoots.
He presents Stitch with coconut juice that he chills with magic, and also uses magic to freeze water and fruit.
With Riddle and Jack’s cooperation he uses magic to repair the door of the cottage during the Stitch event, impressing them both.
He also magically repairs a washing machine.
Lilia uses an unspecified form of attack magic during Spectral Soiree to defend himself against Sebek, and again during Playfulland in an attempt to break down a gate.
In a class he shares with Cater and Vil, Lilia infuses mandrakes with magic.
Lilia uses levitation during the Cloudcalling event to save an opponent from flying into spectators (where he’d physically tossed them by accident), and while the magic he uses during Halloween to eject campus visitors is unspecified, it was possibly also levitation.
Lilia mentions Jack’s outfit for the Cloudcalling being resized to fit Kalim, but as he does not specify which member of the group did the resizing we do not technically know that it was him.
Lilia also uses magic to do his eyeshadow and style his hair.
He seems to use teleportation fairly often until Book 7, when he announces that he has lost the ability to do so, along with the rest of his magic.
