how to recharge your willpower ?
Viewing post in Caliross, The Shapeshifter's Legacy comments
Outside of "one-shot" boosts which depend on certain choices (and are also rare), there are just a handful of ways:
1) If you train with Carla to raise your HP, past a certain point you won't get HP anymore but willpower instead.
2) If you buy Lea as your slave, she can sing for you to increase willpower and intelligence;
3) If you are a noble and you fix the second floor, you can get a relaxation room to increase your willpower;
4) The hypnotist at the circus can boost the stat a little, but repeated uses eventually lowers it (if I remember correctly);
