Est

Est Battle Theme Est is a boss from the Collaboration Scenario. She comes from the game Succubus Quest with Lars and Rovissa, and is the final boss of the collaboration.

She's a Nightmare.

Biography
Est first appears when the White Rabbit comes back to the Paradox World after accidentally opening a portal to the wrong world. She reveals that she followed the White Rabbit in hope of finding another world, just like the legends told her.

The White Rabbit attempts to rebuke her, and Est brings her in her own world, the "Land of Night". The White Rabbit attempts to attack her, but is unsuccessful, and Est tells her that Nightmares can't be attacked like that. She then counter-attack with a pleasure spell that cripples the White Rabbit to the latter's surprise. Having noticed the White Rabbit's unusual powers over space-time, she decides to use them for her own pleasure and summon allies from other worlds with the intent to bring her "Land of Night" to the Paradox World.

She only reappears in chapter 12, after the heroes go into the "Land of Night" thanks to a portal created by Daji. The heroes are shocked at the spectacle, as people are having sex with succubi and Nightmares in an endless void. She finally reveals herself when the heroes reach the portal she used to summon monsters from other worlds, and challenge the heroes to beat her to close the portal.

However, as a Nightmare, she feeds on the pleasure used to attack her, and she knocks out everyone save for the seven heroes bearing the Proof of Collaboration. The party then beats her once and for all and close the portal. She then reveals that she also gave them the Proof of Collaboration to enjoy the desire of seven worlds. Est is happy she got to enjoy such fine pleasures, and asks the heroes if they did enjoy it too. In any case, she bids farewell and leave the party, saying that she hopes she will get to taste more of those pleasure soon.

She later flees to Grand Noah Colosseum, surprising Rovissa who asks her what other plans she does have. Est simply answers that she appreciates the sensuality of the fights, and wants nothing more than to enjoy herself in her quest for pleasure. The party challenges her to have her join them, and, after the heroes win, she says that she will gladly follow them if they can bring her more pleasure, although Rovissa remains largely unconvinced.

First Form
For her first form, Est is just another slightly souped up version of Fulbeua. Like all Nightmares, the strategy relies on using pleasure skills to deal damage, buffs to minimize damage, and steadfast healing.

The only status effect that can reliably land is horny, which is definitively a double-edged sword: You will end the fight twice faster, and she will be more likely to take down one of your party members in a single turn.

This form is fought again in the colosseum with minor stats boosts across the board.

Second Form
The main difficulty doesn't come from the fight itself, but from how well prepared you are.

The difficulty of this fight can be directly corroborated to the number of hero-specific items you got on your way in and how much you used the heroes themselves to farm on your way in. Exploring the Château des Romances to get as many character-specific items as possible while leveling the heroes before facing her is recommended.

The battle itself is relatively classic, as, thankfully, her Nightmare nature is overran by a buff your team is given, allowing you to attack her normally. However, said buff is lost by a character if he dies, even if he's revived afterward. Be very careful. Be sure to have at least ONE hero with a party-wide heal on the frontline like Lauratt. Her fight will be long and tough enough to require a hero on healing duty for the whole duration of the fight.
