You have been trained by the original enforcer, pushing your physical and mental capacity to the limit. Completing the training has given you a way to break past the limit imposed by your race and your armaments.

Your body broken to its limit evolved to a higher state, abilities from your class, subclass and race that uses your wisdom modifier now uses you wisdom score instead and while in combat you gain the capacity to enter a state of Overdrive which boost your armaments and yourself to its optimum capacity. Overdrive can be used a number of times equal to half your proficiency bonus and lasts for 1 minute, while in Overdrive you gain the following benefits:

• You may activate a number of abilities and item that has the same action economy(action, bonus action or reaction) equal to half of your proficiency bonus.
• Your resistances to elemental damages are turned into immunities, and immunities to absorption, but in exchange your armor class is reduced by 3.
• Your body and weapon emits a destructive electric current, your weapon may deal lightning damage which replaces all other damage as part of the attack, once you land a successful attack on a target with lightning damage you may fork the electric current to a different creature within 30ft of the target and make an attack against that target ending your turn at an unoccupied space next to that creature. On a hit that creature cannot take a legendary action.
