"Protego Maxima. Fianto Duri. Repello Inimicum."
Filius Flitwick conjures up magical defences prior to the Battle of Hogwarts[src]

Protego Maxima is a stronger version of the Shield Charm that, when cast in combination with Fianto Duri and Repello Inimicum, conjures up an almost impregnable magical protection barrier.


People who are out of the shield can't see and hear the wizards that are protected. While spells cast at it (if not of enough power to break it) create large, resonating explosions. This spell is the core of the shield summoned around Hogwarts; it is the shield itself that is seen descending over the castle. It should be noted however that on occasion protective enchantments can be breached with a shield penetration spell.

Known usesEdit

  • The incantation is derived from the Latin "protego", meaning "I defend", or "I protect", and "maxima", nominative feminine singular of "maximus", meaning "greatest", or "highest limit"; altogether the incantation means "I protect to the highest limit".
