You're right. This game could be a hit if it wasn't a H-game (nice story, good gameplay, enjoyable side missions). But a kinda 7/10 as a H-game due to lack of sex events and H-scenes. The gameplay and story actually saved the day.
Wow, such an odd and specific ask, and as a first post at that!
Adding to Zippix's reply, things are easy if you're only asking out of personal preference, but do not try the existing version if you have kids around, abuse-related trauma or legal concerns regarding the H content.
You can also just skip the bar scene by not accepting the person's offer to drink. AFAIK nothing is locked behind it so nothing is lost by just ignoring him (outside of an h-scene, which isn't a benefit in this case).
As "that guy" a slight revision: I have also gotten one from a mimic by now, and based on my vague understanding of the loot system I believe it should also (again very rarely) appear in red-icon shops as well as possibly the non-mimic chests in "question mark" rooms. The gambler guy still has the highest drop rate in my experience.
At least for my research purposes the more efficient approach was to faceroll to 42F, save there, and reload with F5 upon making it to 49F without any remarkable drops. General drop rarity increases the further down you go and each dungeon has a handful of semi-unique weapons to collect. As the Nui exploit won't work for that you'll have to stick to regular farming setups.
Interesting, I'll try running the last stretch a while and see if I have better luck. Nothing else has been this rare for me. Though the Nui exploit would still work between 42 and 49 if you just save with full mana, then you can just cast the two spells upon loading each time. Though honestly I still find it easier and faster to rush through levels even at 1hp with the Legion Lance + Supreme Bow Nemesis than to use other weapons. Supreme Blade Hermes + Supreme Bow Nemesis or Explosive Blade is also a very effective combo.
Funnily enough, right after you said that I got it from the very first Mimic I met on floor 43. Took me a bit longer to find a second one after ascending it, but I got it in a shop eventually. The 42-49 trick is definitely a huge benefit, so thank you very much for that tip. Overall I saw way more high-tier weapons lying around. Turns out I'm not 100% done yet anyway though, since I'm missing the Sword Breaker. Unfortunately I'm pretty sure I had that at one point early on, but lost it in a crash and didn't realize how rare it was. Back to the grind.
Explosive Blade is a death sentence, tosses enemies right at you. I agree with Nemesis being the top ranged pick (Bone Needle for getting around town or if you OHKO everything regardless) but in melee I go with the Blessed Treasured Sword. Farming is way easier when you don't even need to worry about dodging most of the time, or can deliberately eat a hit every room to finish the fight more quickly. Also won't break your mouse or cause carpal tunnel if you don't have an autoclicker unlike the daggers/Nui Lance.
As far as I can tell this is merely for "flavour" during the final chapter as the curse became stronger and now starts affecting regular innocent people around you. The heart icon NPCs have their one line of dialogue replaced but there are no H scenes associated with them, or at least none with any artwork.
Totally not a Nui but if you go back through my comments here I posted a pretty extensive item/farming guide. Might be missing the Sword Breaker (Jungle+Residential shop rare find) and Mitum (Dwarven Mine rare find) but neither have any special effects worth mentioning.
