Grinding Stats as of 8.2.3
This list only includes repeatable methods i have tested myself.
These methods may still work in 8.3 but take them with a grain of salt, i've also rated how annoying they are to grind.
- Academics & Science - Insane - Caps at 100, but can be raised to 100 from the Historical society. This grind is absolutely fuckin' miserable, and i actually hurt my wrist doing it.
- Medicine - Hard - The circumstances to max this out requires significant combat, any actions taken after combat to either stabilize or comfort allies will raise this stat with a decent chance.
- Melee combat - Easy - No cap, train it at home or at a way lower rate through combat.
- Ranged combat - Easy - No cap, train it at home or at a way lower rate through combat.
- Stealth & Survival - Easy - Capped at 40 and 60 respectively, Hunting will raise both of these up reliably and quickly. Aquisition rates past these values may have dropped drastically or ceased alltogether.
- Gambling - Easy - No cap, gambling is the ideal method however there's a chance of learning it from carousing too. You don't need to finish a match to gain a stat increase, so just forfeit immediately. I've raised gambling to 113 so it's possible to go higher.
- Performance - Carousing is the only method i've found.
- Black smithing - Great - Caps at 130, creating weapons will have the best results for this stat, and is also a great way to make money. Note crafting clothing/jewlery will also increase Artisanry however it has a significantly worse yield.
- Artisan - Great - Caps at 130, Jewlery and clothing crafting, the best method i've found was making bondage harnesses then eventually gold necklaces, crafting combat armour was the best method i've found to make money.
- Manipulate - Hard - Requesting sex from your slaves has a low rate of increasing this, while farming copulation to it's max i only landed a meagre 58 points in it.
- Charm - Easy - 89 seems to be the current cap for repeatable means. Caress during the seducation will increase it, or you can just buy plastic surgery from the crystal heights doctor's hall if you got cash to splash, Getting 84 charm through being knocked out in combat or caressing until you hit this point will allow you to get surgery and jump to 89.
- Copulation - Easy - Caps at 90, Fuck your slaves and do it a lot, to make the grind easier i heavily recomend getting the evercock implant from the doctor's hall in crystal heights.
- Bondage - Easy - Caps at 70, This one was pretty easy, buy the anal hook from the bdsm shop and just keep inserting and removing it on a slave, high stamina for both of of you massively helps and an autoclicker too.
- Flagellation - Medium - Caps at 70, I'd only rate this one medium because you can't save in the velvet room, so it's tidious, get bondage to 70 through the above method then grind this one by using rough play on the slaves in the velvet room at the dockgrave tavern.
- Cunnilingus & kissing - Easy - No cap, Start seduction with your slaves and exhaust the either kissing option and then the cunnilingus option and just alternate between the two. If you don't want to raise your slaves kissing abillity just do body kissing and cunnilingus.
Now onto the core stats.
- Strength, Dexterity & Stamina - Easy - No cap, no cap and 130 it seems, home training seems to be the best method for these 3.
- Intelligence - Hard - This one is funny, when you create your character in 8.2.3 if you pick all the intelligence options you'll come out with 60 in the public build, you can easily get 60 from healthy sleep from a maxed out bedroom. This is time consuming since your at the whims of RNG but to get to 70 you gamble at the dockgrave tavern, start a match then forfeit immediately and hope, the rate at gaining intelligence from this is extremely low.
- Willpower - Easy - Soft caps at 100, you can go above it through non repeatable events but the best way i've seen is to become an atheist and just attend college to raise your devotion to rank 3 and it'll get up naturaly while.
If you want some advice for character creation, focus on getting academics and science as high as you can and unique bonuses like the free 15 bucks a day, the bonus when charming teens ETC. as a lot of the other just raw stats are kinda useless/easy to farm.
