The vigilante's shield held strong, and he beat the other wizards back until, eventually, he was within a few feet of both. One of the wizards fell down, stupefied, but the other kept casting, walking backwards until his feet hit the edge of a sandpit- he looked down, and the vigilante took advantage. In a rather unconventional way, he punched the robed wizard and expelliarmus-ed his wand. Catching it easily, he pocketed both wands and fought the wizard with his fists.
