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).

Strategy
Lux begins the battle 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.
