Mapping maximized stats greatly depends on what lair you are going for. Sunken temple is by far the worst, while mine offers ALOT more gold potential and spire lets you capture valzira, without losing 1 day to scout her out and having to boost wolf morale beforehand.
Ways to increase strength, without eating the girls:
Prologue: nestle, mount, bite, spit. Then lunge+eat. This lets you start with 2str 1 charm 2 cruelty
ACT II: Lowlands, challenge naho, you fail and get 1str for it. Farmlands, talk to marie. Shelter yields mercy and charming, Pleasure gives potency and charming. Return to farms, eat cattle for another str point. Now you have 4 and that's all you actually need for the rest of the game.
ACT III: You will get an entirely redundant 5-th str point. From then on you can eat even more cattle at farm(6), eat mina's oxen(7), fight 10 men during Mina's scam event for another +1 (8), pay 1 gold to have your kobold attendant
(make something for me-> sacrifice) boost you a whooping, if entirely useless +3 str.(11)
ACT: IV Yet another automatic and entirely useless +1str(12)
For maelys you need to know whether you want to have her as a slave or ally and go through her event in the forests
*DURING ACT II*. Watch her get raped for a +slave point or save her via charm or str check for +ally point. This also makes it so that you need to succeed in only 1 check during the battle at the lair to win her over.
Here is a huge bunch of tips that should be of use for everyone:
Thats all at the top of my head. I might add more if i remember something particularly useful.
