Epel uses magic to levitate a crate of apples during Glorious Masquerade, which he says he also does at home.
He uses fire magic to try and set Rook’s broom aflame in Book 6, and unspecified attack magic to open cages in Tartarus.
Like the other students Epel also creates magical fireworks during Glorious Masquerade.
Along with Sebek, Jade and Idia, Epel also imbues a plushie with magic during the Harveston sled race.
In Book 7 Epel says that he would like to become capable of magically changing his outfit without assistance, so it seems that clothing-change magic is something he has yet to master.
