How else? Have sex. After sex of any kind, I think so long as your character jizzes, the "perk" will be gone temporarily but will come back faster if you have high virility or something.
That's for the Blue Balls series of effects like Pent Up, Rut is a specific condition that used to be a temporary perk from Galvi but is now a status effect that she can occasionally inflict during her scene.
Anyone figured out how to get rid of Rut?
Rut is supposed to fade on its own in time, but every time you sleep with Galvi while under its effects it will be extended another few days. Just avoid the Voltlin for a few days and let it wind down, then you'll be cured. Of course, if its time is not counting down or if it remains after waiting for a few days, then that sounds like a bug that is in need of being addressed.
I do hope that you find this informative,

In terms of update news, Beris still has a couple of more scenes that need to be penned and Amy's art may be implemented with this update as well, depending on how other elements of this update progress and how long they take. One of the most recently written lewd scenes for Beris came in at around 1,700 words and another is about 1,100 words long. Then to make the tomboyish elements of Beris standout a little more, she now says "yo" occasionally in some of her non-erotic content.
Then for other elements for this update, Amy, Shizu, and Ancilla's counter moves have been updated with the new OffenceCounter function rather than continuing to use the AnyCounter version of the counter mechanic. So now Amy, Shizu, and Ancilla will only use their counter moves if you attack during their counter stance, providing an opportunity to heal or buff up rather than only being able to wait or defend in order to avoid a counter attack.
Assuming nothing goes wrong, this update is planned to be ready for this weekend. So hopefully there will be a new Hellhound to look forward to within the next few days. On a final note, for those who are supporters and not yet aware, there is a teaser of another one of the Succubus Campers art up on Patreon, this one is for Jennifer. Once again however, her art likely will not be in the game for some time as the three Succubus Campers are probably going to be implemented all at the same time. So now we're just waiting for Catherine's art on that front.
I do hope that everyone interested in this update news finds this at least a little useful.
