Well, Master Gas's task is complete. This is a powerful monster with tentacles that possesses an extensive set of abilities. A healer is powerless here. A mighty warrior with high willpower is needed, one who is capable of defeating such a creature. Or several such warriors... For once, the indifferent, true nihilists are not useless.
Of course, Ottar was annoyed. Rather, he was angry. How dare this worm take her form?! This thought was much more important to the Blooddrinker than the fact of a pleasant night. He didn't value himself very much when it came to her.
Probably, this creature sleeps or hides somewhere during the day... and hunts at night. It turned out to be quite simple. It's good that he showed weakness and didn't resist. He wouldn't have been able to fight back anyway.
Ottar uses his last available spell cast for partial willpower restoration, takes medicine for the disease, and drinks euthymia. After that, he rests a little, changes into simple clothes, and heads back to Gas. The road will not be easy... but what can you do. The healer's duty calls.
Of course, he could distribute the medicine to the whole village, but it doesn't really make sense as long as the creature is alive. Now she has a tasty hunter with refreshed blood for dinner. And the rest of the peasants are doing well anyway.
