Sister Lamia

Sister Lamia is a monster nun who is devoted to Ilias, however her status as a monster makes this seem difficult.

She first encounters Luka and greets him on his way to the city of Grand Noah, disguised as a human, however Alice calls her out to reveal her true form. As Luka draws his sword, Sister Lamia reveals to be a devotee to Ilias and does not attack. She informs them that Noah is a particularly friendly region towards monsters and tells Alice that she has no need for her own disguise. However, the south is not monster-friendly which why she has her disguise. Putting it back on, she wishes them well and leaves to the south, attempting to spread Ilias's teachings.

In Chapter 3, Sister Lamia is one of the attackers of San Ilia.

Monsterpedia Entry
''“An extremely rare monster that is a pious believer of Ilias, despite her teaching against Monsters. She was solicited by Black Alice to head to San Ilia itself. She is no acting as an advanced unit, following Ilias’s commands directly.'

''After being granted an artificial spirit, her power and strength drastically increased. Any prey caught in her snake body has no choice but to give up. When carrying out Ilias’s order, she will show no mercy whatsoever at devouring male’s life force, despite her gentle nature. While embracing her prey, she will try to reassure her prey as she squeeze them dry.”''

Battle Overview
This battle is more complicated due to her ability to use Earth Spirit Summon in which will present an unescapable bind with Ecstasy Snake Wrap via follow-up and enhances her damage for the next turn after that, resulting Fallen Angel Dance needed. Her Holy Snake’s Invitation will lead to Holy Snake’s Embrace if attacked within three turns as well.

Evaluation
''“Did it feel good to die in a Lamia’s embrace? It looked so good, my mouth was agape the whole time. Since she is a monster, a serene state is effective. But her attack patterns are very troublesome, unlike most monsters… First, you must never attack when her breasts are exposed. If you do, you’ll be guaranteed a loss. In addition, she has a chance of using a troublesome magical eye move. If you want to avoid that, you’ll need to switch to fallen angel dance right away. Another problem arises if she summons an earth spirit. If she gets you in a bind after summoning her, then you won’t be able to break free. The opposite to earth is wind… But you don’t have Sylph at the moment. So you’ll have to use the next best thing, fallen angel dance. It has a wind property to it, so it will let you dodge her binding move. I’ll tell you more about opposite attributes later… The battles will only get more and more difficult from here and out. Now go, oh brave Luka. In the end, monsters will always be monsters. The only thing they deserve is the wrath of the Heavens.”''
