depending on what character I have. I often raise my spring attack and crushing blow first and formost. I also use uppercut since this is very important for harpy and bee encounters(damn harpies divebomb me and bees are pretty tanky). For a level 1 chaste virgin run of the game, i dont suggest investing in magic or charisma since they just kinda suck late game (lots of the bigger enemies are resistant to magic and hit too hard to waste a turn and charisma is only used for fun, when the physical abilities offer outs as well). If you are going for say a level 1 run, but not a virgin i suggest getting buttfucked by ghosts as much as you can in the beginning without gaining too much xp since you can gain perk points from that. If you are doing the chaste run separately as well, then you can invest a lot into physical abilities AND magic because embers is really really good against tanky bees because once they are on fire they stop drop and roll giving better hits for spring attack and crushing blow. You should only steal the diamond plate armor when your agility is like 9 to not get caught, as well as not stealing anything else from anywhere.
My runs consist of going to town of humans, asking brothel madam for job with more gold, then going to town square, asking about goddess, eavesdrop and get the gem, buy all the food at the store, go to blacksmith (If i have a high agility i steal the diamond plate armor) and purchase the dagger and the broadsword(after i steal), then i head towards monsters, purchase the helm of perception and boots of agility and go to the pub for brothel madam quest, then head for witch's cottage giving them gem and persuing their wares to attempt to steal their agility charm and purchase the cage of power, then i head for the verdant valley where the giantess is, I make sure to have high perception and stay away from the giantess, obtain gloves of power and 100 gold from giantess and decide to be eaten, leave, go to goddess and it should be easy to beat her at this point, then I go to the altar (backwards usually, since it is in between monsters and the xinxu mountains where the goddes is) and teleport back home, go back to brothel madam and recieve more gold for the quest and go to town crier for reward for goddess, (purchase battle skirt if i do not have one), go to witchs cottage again and attempt to steal strangth charm, but if unsuccessful, just purchase strength and endurance charm after already owning agility charm. If you could not get agility charm first time around purchase that and strength charm instead, then head towards the demon king from there (yes i know there is a lot inbetween but you should have all of the gear you need).
In the beginning of the run there should be a hunger charm in a cache nearby the town, make sure you use perception in order to find it or scout out for it and make sure your scouting level is 3 right before you get it in order to ensure that you will own it. Also if you have low charisma, i suggest picking up trudy if you can, and if you cant use high perception to avoid werewolves. also if you feel really cautious of werewolves and have high strength, use a perk point on scentless. Picking up kylira is nice,for an actual run, but not for a level 1 chaste virgin run.
I suggest this to not be the first ironman run you have done, since there is also all of the other achievements i strongly suggest you complete in order to get an extra edge in the beginning. Also I suggest running orcblood for your first time around.
ducking and upper cut is still viable laate game because the demon king will pull a few haymakers every so often. Also spring attack and crushing blow are still very good and it is what i suggest you use on the demon king.
Food can be obtained later in the game from merchant food carts, flocking harpy eggs, sleeping ettins, and (not a lot of food) briggand cottages. Healing pools are less common but i suggest that you drink from the waters. I didn't and i was fine because i always want to try the encounter again when i am done because i just like having the option but if you encounter a healing waters again, you WILL loose some purity because they will kiss you regardless. So i strongly suggest that if you encounter a healing pool to drink.
having low charisma and low magic in beginning may be difficult to deal with ghosts and dryads(for food), but are less common late game so you should be fine.
If you go directly to each point i listed above, then you definitely shouldnt run out of food.
any other questions you may have?
