Doppel Luka

Doppel Luka is a monster created by Promestein, intended to mimic Luka's physical appearance, memories, and abilities. The clone is also capable of changing its gender.

Monsterpedia Entry
"A clone of Luka created by the pinnacle of Promestein's genetic engineering technology. But her gender isn't set, and can be switched between male and female at will. She was created using samples taken from Luka during the Wormiel fight, and has all of his memories and physical abilities from that time. When she takes a female form, her thinking and personality also changes to become more feminine."

Battle Overview
Doppel Luka is quite difficult as she can offset all of Luka's offensive skills with her own. However, if Luka uses Element Spica (which appears after using any offensive skill), she will strip and begin using more elaborate attacks, but she will no longer offset his attacks, so use Undine to counter.

The achievement "Defeated Doppelganger without her unclothing" can be earned by defeating Doppel Luka without her unclothing, that is, without using Element Spica. This can be done by alternating between Gnome, Meditation, and normal attacking.

If Luka fails to withstand his copied self, he is raped by her vagina and forced to repeatedly impregnate her.

Evaluation
"You raped yourself...? Couldn't this just be said to be some elaborate form of masturbation? Doppel Luka can offset all of your sword skills. You can't fight her directly without addressing that. You should check each of your skills against her, and perhaps try to find one she doesn't know... After she strips, you can fight normally... But you should give priority to rebuilding your SP. In addition, depending on when you lose, it will change whether she's dressed or not during the rape scene after. Oh I wonder what you're going to try now!? Now go, oh elaborate masturbator Luka. Because you disappointed me, I can tell you're the real one."

Trivia
