Aegis Inorum

Aegis inorum is a ritual spell invented by Minasaer Neriqen. He invented the spell in 810.

The spell requires an intricate ritual which physically strengthens the atomic and molecular forces of the object on which the spell was cast. The bigger the mana source, the stronger the force increase. When enough mana is used, this can make an object virtually indestructable.

The only known way to disrupt this spell is to destroy the source of mana or to overpower it with an even stronger source. The source should be at least twice as strong to properly disrupt the force field. The field is only disrupted as long as the force from the other source is exerted on the abjured object.

When attempting to alter the structure of the object on which Aegis Inorum was cast, the bigger the force exerted, the stronger the magical field around it gets.
