Lorelei

Lorelei, or Heine as a companion, is a monster in the second part of Monster Girl Quest: Paradox.

Monsterpedia Entry
''“A mermaid of the highest class living beyond the great waterfall. Her lineage is closely linked to the ancient progenitor species, and their numbers are very few. In addition to boasting a strong body and great magical power, her singing voice can water down any man who hears it.''

''Her ability to express emotion is poor, but she has a deep obsession with men and if she sees one, she will take him by force to become her husband. In addition to whispering her song of seduction into the man’s ear as she hugs him, she will also thoroughly wash his body with the soapy bubbles that seep out of her skin, immersing him in ecstasy. Once he has been watered down, she will intersect with him. Of course, Lorelei’s vagina is also amazing, and any man who tastes it will never want to leave her side again.”''

Strategy
Warning! This fight might cause RAGE. She can heal herself for tons of HP using Rain of Life. Thankfully, it has its own internal cool down (6 turns), but it will certainly put a damper on anyone who fails to burst her down. Therefore, either silence her or put her under an effect that prevents her turn from happening like bind or stop in order to avoid pulling your hair out. In terms of offense, Maelstrom is a rather strong water attack that will be even stronger if she has cast Mass Enchant Magic beforehand, and all her sex-based skills can make short of work of weaker party members if she uses Mass Enchant Technique first.

As Ilias below says, use lightning and earth elemental attacks to quickly bring her down.

Evaluation
''“You ended up as the mate of a high ranking mermaid… You stink of fish, so please keep your distance. Lorelei is the highest ranking mermaid. Her techniques include White Magic, Ice Magic and Tsunamis. Since she is a mermaid, she is weak to Earth and Lightning. Binding, Blind and Paralysis are also effective, so make use of those. Now go, oh Brave Luka. Have sex with birds and fish alike and conquer both the sky and the sea.”''
