trigger master
This character has extensive practice with genjutsu "triggers." They can swap around the triggers of their genjutsu, and increase the effectiveness of those triggers.  Note: This perk allows an individual to enhance a trigger or replace it for another trigger.  Examples include:
If one were required to stare directly at a vase for several seconds, this perk could cut that time, or change the trigger to the vase being in peripheral vision instead.
If a vase is the trigger, it could be replaced for a related sound such as the Vase breaking.
Proficiency Perks are required to change a trigger from one type to another.
