Amorous Snakes appear throughout the Monad Depths within Tartarus. They will attempt to heal themselves or assist knocked down allies if given the opportunity.
Persona 4
Amorous Snake first appears as a sub-boss on the 7th floor of Marukyu Striptease within the Midnight Channel. After navigating around the floor after Shadow Rise turns the lights off, the party will come across a curtain that gives a warning about entering. The Amorous Snake must be fought to continue the dungeon.
It will later appear as a normal shadow on the 1st through 3rd and 6th World of Magatsu Mandala. It will use Stagnant Air and Poison Mist to Poison the party and Life Leech when injured. After being defeated, it may drop a Scaly Lump. Selling 4 Scaly Lumps will unlock the Phalanx weapon for Kanji Tatsumi in the shop.
In Golden, Amorous Snake appears on Magatsu Mandala Worlds 1 through 3. It may also be summoned by Chaos Fuzz. Upon defeat it may drop Angelite for trade at Shiroku Pub.
