Wizards Always Get the Last Word

Triggered the next time you access the map, at least 2 days after completing "the bathhouse opens for business" and "the war ends - the war (part 5)".
A short scene will automatically trigger and mark a spot on the map, make sure you are ready for a long battle.
Selye’s fight is divided in 2 phases: in the first one, he has 400 HP and is surprisingly vulnerable to teasing, making it a good strategy to save your potions for the second phase, unless you have high STR and AGI and can brute force your way to victory; the naga will very often focus and cast 5 high damaging magic blasts on the next turn, defending is vital when the game warns you (with a prompt on the top left of the screen), otherwise, he has a weak single hit spell or can use the emblems to focus and lower his lust by about 20, overall, not a difficult fight, consider using a HP potion before winning, and MP potions too, if you used MP for some reason, so you are ready for phase 2. He will start with 300 HP regardless of how phase 1 ended, as his looks suggest, his attacks are gonna be way stronger, but hit only once, and will obviously reject your teasing. strong builds should attack and bind up when needed, depending on their max HP and bind up healing, which might be lower if they didn’t focus on END and INT at all, if things get dangerous, focus on defense by binding up, using a MP potion and defending before you can bind up again; builds with higher INT should stick to holy fist, bind up if needed, and using more MP potions when possible, Selye doesn’t hit too hard, so having a higher INT, and presumably a good END, will make sure binding up heals more than enough, while the cooldown turns can be used to stall by defending or doing chip damage by attacking, if a potion isn’t needed.
Losing during the first phase actually gives a sex scene followed by a bad end, despite Caro not hinting at it in his post, and Selye not liking you~, but try not to die during phase 2 if you hate gorey deaths…
Winning has you kill the wizard, regardless of your choices, unfortunately, 3000 EXP, and you won’t get stat points, but the level cap raises from 15 to 25, and the stats cap from 10 to 15! Chet will also start selling better HP potions (HP potion +1), at the same price, which heal 110 HP (any HP potion you are carrying is also upgraded for free, that’s some good customer service~ they are +1 in other shops too!).
The skull emblem will also fly away, but at least Nauxus will give you the star emblem after telling him about Selye, while he’s close to the tavern (this means that you won’t get the star emblem if he had more than 3 suspicion points!) (and don’t worry about the dragon in the painting, see below).

Other than the quest itself, 0.19 laid the bases for the game’s second arc, this includes some new areas important for later updates:

• A cave beyond the broken bridge on the trail to the bull temple, which contains a statue of the mysterious dragon in the painting; asking him about that has him reveal you his name, Máng, and changes the available dialogues.
  Note: even if you don’t have 2 emblems anymore, Máng’s magic will make sure the painting stays accessible.
• The area close to the cave can’t be explored yet
• The sand wall on the far north-west of the map, where you meet and save Horace (only after killing Selye); he’ll wake up while you are visiting the mountains. If you didn’t meet him, Snow will tell you he was saved after coming back from there, so he’ll be fine regardless.
