Tarsa

The true form of Novissa's companion is a succubus added in the Collab Scenario. She comes from ROBF4SU with Novissa, Mysteltainn, Ogretooth and Executioner

Biography
Her Succubus properties get awakened at the end of chapter 3, when Musette reveals herself in front of Lest, and then violates him under her order.

She's fought at the end of chapter 7 by Lest and Novissa as she's sucking men dry for a ritual to bring in the Château des Romances, and engage the duo in a fight. She recovers afterward, and enters back into the team's fold.

A clone version of her is later fought at Chapter 12 in Finoa, when Myusca creates seven challenges for the heroes. She's involved in a game of "karaoke handjob" where the party must score a high mark at a karaoke machine, and breaks the concentration of all four heroes that participate, making them fail hard. However, the hero's party notices a loophole as the rules don't say anything about beating her up. Myusca accepts the solution, but asks if the party can really be called heroes afterward.

Chapter 7
Like most succubi, she isn't exceptionally tough but her status effects can be annoying. Equipping Trance Guards or Trance Checks can prevent the worst effects. However, since your healing capacities are limited at this point, equipping Zeal Ring can also be useful. Otherwise, focus on attacking her with your most powerful moves.

Real Fight
An appetizer before the Succubus Prison trio, she's just yet another succubus boss, with her status effects and pleasure attacks. Keep attacking with ice or holy, and if you fail, leave and grind your team until you can beat her easily, otherwise the fight ahead will wreck you in a heartbeat.
