Sex God
From Portals of Phereon Wiki
This skill can be unlocked by reaching God-Rank in at least one sex skill.
The requirement for the main character is rank 10 in one of the sexual skills in your Date Deck.
It does everything Sex Master does but better, while also removing the Vulnerable effect from sex in combat. Amazing skill to have on your recruiter, and great at helping your low LRes units when they are high on lust.
