Gilgorn

Gilgorn is a boss from the game Succubus Rhapsodia. She's the boss of chapter 10, and the original lord of the Château des Romances

Biography
She's first seen in chapter 10, clearly annoyed that her castle has been invaded by nightmares and wary that she's in another world. When she notices the party, she thinks that they're Nightmares here to finally take her down.

After beating her down, she relents and accepts to help the party to fight Nightmares, asking them why didn't they ask sooner, ignoring that it was the first thing they did.

Strategy
Since you have access to your whole roster, your options will be varied. She possesses a large slew of status effects that are once again the real threat to this fight.

She is EXTREMELY WEAK to pleasure attacks (300% damage) and related effects. If you recruited Alma Elma, she will turn the Demon Lord into her breakfast in a few turns with Lilith Orgia.
