Dark Elf Fencer

The Dark Elf Fencer is an elven monster that patrols Enrika. She is the first elf encountered in the game, albeit one which has fallen from grace due to devoting their mind, body and spirit to depravation.

She is also capable of using a sword, hence her name, however Luka easily sees through the ruse as a ploy as she goes on to using various pleasure attacks. As she has fallen to darkness she also holds some dark seductive powers, using her kiss to enrapture men before using her tainted body to corrupt them and make them just like her, devoting themselves to carnal desires after their soul has been sucked out by her genitals.

She confronts Luka seemingly to turn him away from Enrika, as does the Dark Elf Mage after her, only to be sealed and shrinks into the size of Luka's palm. Despite her dark disposition she seems to be a guardian of the surrounding forest, though her intentions may not be so clear cut, due to her nature.

Monsterpedia Entry
''“An elf who has fallen to corruption is normally referred to as a Dark Elf. Giving into the darkness and degeneration of mind and spirit, their bodies turn black.''

''Though able to live as herbivores, Dark Elves prefer to have intercourse with humans and feed on semen. With magical power flowing through their sexual organs, they will violate men and corrupt them. As soon as the male ejaculates inside of them, they will fall into darkness. Once that happens, the male forgets about everything but pleasure. Like that, they will single-mindedly have sex with the Dark Elf until they waste away.''

''Once the Dark Elf is corrupted, they lose their reproductive ability. Their only purpose in attacking men is to sate their appetite lust.”''

Battle Overview
With not much in the way to use different strategies, the battle against the Dark Elf Fencer is purely to outdamage her and hope she doesn't use Kiss of Ecstasy, her trance attack, as there is no way to avoid it. Other than that, her attacks are just normal ones.

Start with Demon Decapitation and use it whenever the SP requirement is met. Always be on the offensive, the strategy is to beat her before she beats Luka. Her Kiss of Ecstasy can complicate things as Luka will be unable to act for several turns.

If Luka succumbs, the Dark Elf mounts him and uses her dark powers to corrupt him by forcing pleasure onto him and absorbing his soul. After the initial ritual, she and Luka consumate their lust until he dies.
