Some of the most useful skills I’ve discovered so far; will update as I find more.
Strength
Acquisition:Sleep early for 3 days in a row. The game says ‘before 12:00’ but this is clearly false. I suspect it’s meant to say 22:00.
Effect:+1 to all stats as long as you ‘have no sleepiness’. This is a extremely easy criteria to fulfill.
Agility
Acquisition:Read the book of the same name.
Effect:+1 to Dexterity(Notably, Stealing)(NOT AGILITY. Dexterity is a subskill.) checks and halves the time they take.
Iron Throne:1 SP
Acquisiton:Gain the ‘comfort’ status effect 5 times, acquired by using a toilet with high enough Digestion.
Effect:Gain 10 stamina whenever you use a toilet, and halve the time it takes. This adds up–10 stamina is equivalent to a half hour of rest. That means that if you use the toilet whenever you can, you save 25 minutes of rest each time. And if you just use the toilet when you need to, you save 35 minutes.
Intelligence
Acquisition:After you get through a certain amount of the main story, you will receive a unwanted guest. Pick the calm responses. This will cost you some Mind. The outburst at the start of the scene does not count against this.
Effect:-1 to target number when you use Focus to reroll a failed roll.
DIY Maestro:1 SP
Acquisition:Book.
Effect:+2 hidden storage compartments in your cupboard. More storage is always good.
Dishonorable Mention: Geek.
Acquired by crafting 10 times. I would only consider grabbing this if you also have Memory Palace, and only to toggle it on before doing something like reading for a while. Every stat point matters and -1 Charisma for +2 Intelligence is…bothersome.
Charisma
Acquisition:Book.
Effect:Allows you to craft Bandanas from 4 paint and 1 cloth. One swaps crit for dodge, the other does dodge for crit. More importantly, adds 1 Charisma to bandanas.
