Kadonk is a spell exclusive to the Joker sub series of the Monsters spin off games. When cast, it reduces the target's HP by a fraction of their current health. Resistance to this spell is based on accuracy, similar to Dazzle and Sap.
Kadonk is learned through the Cursader, Exorsus, Wormonger, Zenith Dragon, Wildcard skill sets, and costs 32 MP to cast. It affects all enemies on screen, and damage inflicted is 1/6th of their current HP.
Kadonk's damage calculation is the same, but now only targets one foe. MP cost has been reduced to 8.
