A sub-class of magi that specializes in the ability to nullify or “dis-arm” magic. They are particularly good at taking Æther Field endowed objects or locations, and “cleansing them”. Think like a bomb diffuser.
Advanced nullifiers have the ability to negate spell sequences in real-time, spotting spells before they finish compilation.
Even more advanced nullifiers can nullify spells after they have already been casted (mid-flight), but this is a rare ability and usually it comes with years of training and practice. Most of the time it only pertains to spells that they have specifically trained for.
The difficulty of nullifying spells is proportional to the technical prowess in casting any given spell. More advanced spells require more advanced disarmament techniques.
Partially nullified spells can the capability of being even more dangerous than their original intent.
Because of the defensive and non-escalatory nature of nullifier abilities, they are a vital resource to have in the pbi’s Section 11 arsenal.
