Against normal monsters, Zantetsuken inflicts Death.
Not 100% accurate. Accuracy decreases as the number of enemies increases.
Inflicts Death on enemy players in Ballista and on Charmed players. Ballista players may avoid instant death by resting or kneeling.
Against Notorious Monsters, Zantetsuken deals ConalDarkness damage instead of causing Death.
Damage is based both on the summoner's remaining MP % and the current HP of the NM. Damage decreases as the number of NMs increases.
Zantetsuken's damage can be decreased or nullified by NMs with high magic resistance. It was resisted completely (0 damage) by Hydra with magical shield up, as well as Jailer of Temperance (which has innate 100% magic resistance). Zantetsuken dealt significantly less damage relative to Jailer of Love's remaining HP.
Can do a maximum of 9999 damage before modifiers.
Mana Cede can be used, if timed right, to enhance its damage further.
