Ending S - "The god of ultra-violence"

The Outlander's specific ending that is only achieved by him while playing in hardmode. To do so, he must slay a number of monsters and foes and acquire their souls. He can also acquire said souls from using empty scrolls too.

The monsters you need to slay in order to achieve this ending are these: In order to acquire their souls, you need a soulstone (except the Black Witch. Simply defeat it and you will acquire their soul from their defeat).
 * Black Witch
 * Iron Shakespeare
 * Butterfly
 * Crow Mauler
 * Cavemother
 * Salmonsnake
 * White Angel
 * Tormented One
 * Valteil
 * François

This can all be bypassed via the exploit of using the Empty Scrolls you can get from searching bookshelves. If you get lucky that is with the RNG.

After achieving these unique souls, a message will pop up, saying about sensing that all of the evil in the dungeons have been cleansed. After receiving this message, simply leave the dungeons via the way you came.

That's it. Enjoy Ending S - "The god of ultra-violence".

Tips

 * Try to get Isayah's Iron Mask via killing him, since it will help against Crow Mauler's Flock of Crows ability.
 * Not recommended to do this alone. You can get help via Necromancy, Blood Magic, and the Demon Seed, as getting and recruiting the normal companions is disabled in Hardmode.
 * Try to get Miasma as soon as possible.

Trivia

 * The monster that Ragnvaldr slays in the picture in his Ending S is a creature that looks similar to the NPC, Iki Turso.
