Which doesn't work half the time, and is pure RNG if sexable NPCs even spawn or not.
For example, this last run I did, in 6 gameplay hours not a single fuckable goblin spawned. I still can't even interact with goblin princess because my reign affinity is only 1 (Lizz is never up to fuck either).
So if I picked a Monster Eater knight, I would have never climbed out of the negtive affinity. It's pure RNG.
Treating everyone drinks in Faun's tavern is the best (but still purely random) way of getting reign affinity. Doesn't help that most of the time tavern patrons are dipshits like Lamias or Driders who don't have their own reigns.
Now you'll suggest another game-breaking exploit, or to use cheats - but then why even play the game, might as well just google the fucking CG-rip.
This is a tip starting from nothing.
Step 1: Pick Guild Knight.
Step 2: Get the candle from Kobold Princess.
Step 3: As soon as the game starts proper, head immediately to Skelly Princess church and get the Death-not book.
Step 4: Visit as many places as possible to find skeletons and get a complete set (One Head, One ribcage, and 5 whatever else). Step 5: While doing this make sure to do and complete guild quests every single day. Aim for easy to do quest over higher exp quest you don't want them taking up much time.
Step 6: When you have a full set, make a skelly slave.
Step 7: Head to Slime Princess's Slime Pool.
Step 8: Go up to the orb and save your game. Now use the orb to bring life into your skelly, you're aiming for a dragon. If you don't get it, reload until you do.
Step 9: Equip your best gear on that dragon, make your weapons two fist weapons and give her the candle for accessory.
Step 10: Use the dragon for all combat, they should have stupid high atk power, atk speed and luck.
Step 11: Buy Family Jewels as soon as you can.
Step 12: In-between doing guild quests, try to visit these places everyday until you've gotten your Knight or Dragon to lvl 20: Golem Area - Battleground (Kill the golems and pick up cogs), Mouse Area (Look for NPCs to screw, turn in cogs, buy wings and gas mask), Beach Area (Look for NPCs to screw), Goblin Area - Brewery (Look for NPCs to screw), Tavern (Quests, sell stuff if merchant princess is there and yup look for NPCs to screw), Kill any bandits you come across, they sometimes drop pretty good loot.
Step 13: Once you've gotten your Knight (focus on getting all stats to 5) or Dragon to lvl 20 (focus mainly on combat stat), start hunting down the mimics for Mimic Princess.
Step 14: Once you have her and the Mystery Box (DO NOT USE IT), work on getting the wings and gas mask.
Step 15: Once that's done, hopefully your guild level should be 5, get the banner and head to places full of NPCs. Beach is the best place. And try to recruit at least one of as many races as you can.
Step 16: Once all of this is done, make sure you have a club weapon, deposit all swirlies into the bank and head to the Southern region. Go due east and fly using the wings to the island nearby.
Step 17: Make your north, using the club to break rocks. Jump in the hole. Get the crstal princess if you want, break the northern wall, and head keep heading north.
Step 18: You're now in the lands below, equip the gas mask and head to to the first southern path into the poison and go to the ruins. Instead the ruins, look for the turtle shell that glows. Now, this next part is highly important. Unequip EVERYTHING of value from all characters you currently have except the gas mask from knight. Once done, use the Mystery Box.
Step 19: Walk inside the glowing turtle shell and wait. When prompted, stay in the shell. Your run just ended.
Step 20: Start new game+ and rechoose Guild Knight, get yet another candle from Kobold Princess, open the Mystery Box and do whatever for the first two days.
Step 21:Once you get access to your Progencies again, take out your dragon. Re-farm cogs until you can buy gas mask annnnnnd......repeat Steps 16-20.
Step 22: Re-choose Guild Knight once more, and now you're ready for your serious runs. With Guild Knight++, you no longer have a daily limit on quests. Use this to your advantage and get Knight up to 30 asap. Recruit any races you don't have as companions, get their level just high enough to give them 5 love and lust and use them as affinity batteries.
