Mahamaon

Mahamaon (マハンマオン, Mahanmaon)^? is a special Expel skill.

Effect

Mahamaon has a medium chance of instantly killing all enemies. The skill instantly drops the opponent's HP to 0, by 40% chance, with resistances decreasing the odds and weaknesses increasing the odds.

Bosses are always unaffected by Mahamaon's instant kill abilities, even if they are weak to status. The method this is done depends on game; if no damage-dealing Light or Dark skills are present, then the boss is naturally immune to Light and Dark. If said damage-dealing skills are present, then all instant kills are blocked by the boss even if it is weak to Light or Dark.

In Shin Megami Tensei IV Apocalypse, Mahamaon does heavy Light damage instead of instantly killing the enemy. If the user is affected by Smirk, it will instantly kill any non-boss enemy. It will only deal damage as usual against bosses.

In Digital Devil Saga: Avatar Tuner, Mahamaon reduces the current HP of all enemies by two thirds but in Digital Devil Saga: Avatar Tuner 2, it reduces the current HP by four fifths. Should an enemy be weak to Expel, Mahamaon will be guaranteed to remove the corresponding amount of that enemy's current HP. Human characters (both party members and enemies) are always immune to Mahamaon, even in Berserk Mode.

In any game where no damage-dealing Light skills are present, the skill is Light type. Otherwise, the skill is Bless type.
