Kaiden Musha possesses primarily Physical skills and a boosted Mahamaon, and is the next most dangerous _target in the boss fight after Onnen Musha. Damaging it would prove risky as it can randomly reflect physical attacks with High Counter, while the Tenjin Musha possesses Makarakarn to reflect elemental spells. Fortunately, most party members will be outright immune to the element they cast, so pelting it with elemental spells would be a reliable means of consistently damaging it.
Persona 4 / Golden
Rain End Musha appears in Chapters 5 and 6 of the Void Quest within the Midnight Channel on rainy days. It repels all four elements (Fire, Ice, Electricity, and Wind), uses Power Charge to strengthen its attack (just like its Persona 3 counterpart), and possesses the passive skills Sharp Student and Null Dizzy. Also, while it is not strong against Physical attacks, they are slightly reduced by a hidden resistance modifier. When defeated, it may drop Rain Steel. Selling Rain Steel at Daidara Metalworks unlocks the Ama-Gakure male armor for sale, which has the lowest Defense of armors available during the Void Quest but heightened Evade and an Agility boost of 10.
In Golden, Rain End Musha appears on Chapters 3 to 5, 8 and 9. It may also drop Howlite, Milky Quartz or Bloodstone for trade at Shiroku Pub. Selling four Rain Steels will unlock the Ama-Gakure.
