Trying to get to the very end without fucking to get two achievements with one stone. Problem is, the game is hard without fucking, which, fair, it is a porn game, but I want to achievement hunt, so I need to do this. I can tell I want jacked perception, but aside from that, dunno. Any help is appreciated!

Get your perception way up. More so than anyone fight, mimics are the biggest threat to your chastity. You effectively need max perception whenever you walk into a chest. I think 7 plus surveyor can let you do this without wasting food to check, but I would need to double check.

Otherwise just a strong combat build should do. Agility is more important than strength, as it effects balance and some weapon damage. Plus it lets you avoid some nasty events. Honestly it is just a matter of saving often enough to try fights where losing ends chastity. Most enemies are easy to figure out with multiple tries.

Once you have some strength, don't be afraid to grapple and throw when you can. It is surprisingly effective at dealing damage while staying safe.

Very hight perception is not required to be chaste. Mimics are only met on Artifact cache tiles. They're avoided if you get your scouting level to 4, which can be done just by pressing the chest button and using up some food.

The game is pretty easy when you learn to make strong builds. I usually put everything into Agility to have it at 12, make Perception 5, Strength around 4-5 and Endurance 5-6. I buy the stat raising gear in the second town. I steal the good armor, better use Diamond Cuirass or Full-Plate, but they can waste your stamina as they weigh a lot. I also steal good weapon and reinforced shield, steal charms, and it's enough to make battles a breeze.

There are various possible builds and slightly different tactics, but they're not so different in the end, pass Stat checks and get stronger, tougher, more stable than your opponent, learn skills to counter their moves.
