Lux of Lust

Lux of Lust (色欲のルクス Shikiyoku no rukusu) is a boss in Succubus Puttel associated with one of the seven deadly sins, specifically lust (luxuria in Latin). She initially appears in Radisasu Ruins] as the boss of the area. In versions 3.0 and later of the game, she reappears in Empress Place with greatly increased stats and some new skills. Defeating her second incarnation weakens Bosewicht.

Profile
''The succubus who commands the sin of lust. With a figure and skills suitable for the title, she can extract the semen from any man. Surprisingly, she's actually a graceful person. She may become a special lecturer for the Succubus Training School.''

Strategy
In the first battle, Lux begins by using Deadly Sin: Lust, which maxes out your Lust meter and inflicts a debuff that increases the rate at which it fills. It's therefore essential to have plenty of Lust-removing items for this battle and to use them liberally. To defeat her, use Mouth attacks. Her unique Lustful Prison skill puts you into a Hold in which most of your Mouth skills (except Kiss) are sealed, so Struggle out of this Hold as soon as possible if she uses it.

In the second battle, Lux no longer uses Deadly Sin: Lust. However, she can now use the Ecstasy Charge skill, and the second time she uses this, she immediately follows it with Lustful Temptation, a powerful Hand attack that can potentially kill you instantly. To survive this, you should use Endure: Hand whenever she uses Ecstasy Charge. Afterwards, Lux will use Ecstasy Break, which is essentially doing nothing, giving you the opportunity to heal. Again, use Mouth attacks to defeat her.
