The Spellsplinter Maneuver is a fighting technique that allows one to interrupt a caster's spell, even if the caster is casting defensively. In the present day, the only known living fighter known to know the maneuver is Roy Greenhilt, who was taught the move by his grandfather Horace in Paradise. Roy has used the move against three opponents: Against an illusionary Xykon while under the power of Girard Draketooth's illusion in his pyramid, Miron Shewdanker while fighting the Vector Legion and the Empire of Blood and against the High Priest of Hel at the Northern Godsmoot. The last use, which was the first time he used it publicly, greatly surprised those assembled at the Godsmoot given that they believed nobody who knew how to use it was still alive.
