Invy of Envy

Invy of Envy (嫉妬のイビィ Shitto no ibyi) is a boss in Succubus Puttel associated with one of the seven deadly sins, specifically envy (invidia in Latin). She initially appears in Onslaught Forest 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 envy. Because her self-esteem is low, and she thinks nothing she does will matter, she becomes depressed when thinking about others. She can't stand it when others have something she lacks.''

Strategy
In the first battle, Invy begins by using Deadly Sin: Envy, which inflicts a debuff that lowers your ability to recover Vigor. For this reason, you should use Chest attacks to take her down as soon as possible. Her unique Oblivion Restrain skill puts you into a Hold and is followed by Oblivion Grind, so Struggle out as soon as possible if she uses this skill.

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