My thoughts are madness and insanity are things that many people have complained about while others have no issues with the feature at all. I know in towns where people have specific skills IE mining some people may have issues with madness because their tasks are heavily dependent on things that do not reduce insanity while others a full time cook for example never have issues with madness via always reducing insanity. So I propose the following:
New skills
Totemism
3,000 Faith & Wisdom
2,500 Law & Lore
1000 Arts & Crafts
1000 Woodworking
500 Flaura & Fauna
250 Natural philosophy
50 Perennial philosophy
New Structures
Unlocked with Totemism: Rudimentary Totem (movable)
10 woodblocks
5 hay
3 sharpened sticks
4 branches
10 stone
Increases insanity reduction by 2x when performing calming routines.
Unlocked Totemism and Kiln Construction: Clay Totem (non-movable)
30 clay
20 bricks
2 Golem of Prague
3 misshapen lump of clay
2 wooden handles
2 pig iron bars
Increases insanity reduction by 4x when performing calming routines.
Unlocked Totemism and ceramics and crucibles: Pristine Totem (non-movable)
50 bricks
10 mortar
10 gold eggs
20 cut gems anytype
2 wooden paddles
10 oiled boards
2 wrought iron bars
Increases insanity reduction by 10x when performing calming routines.
Unlocked Totemism and waste: Malevolent Totem (non-movable)
50 bricks
20 mortar
20 fractured gems
2 blood soaked cloth
2 madness broken tools of any kind
20 turkey poop
40 moldy boards
Increases insanity gain by 20x to people in range (torchpost range) who are committing waste to any type of wall or brazier/torchpost.
I think having structures that can help increase the insanity management may calm a few loud people down. Bring more diverse structures into the game. Adding a malevolent version also allows for people to be less disappointed when their prized pickax or shovel because questionably effective and also adds an additional raid mechanic that makes things interesting. I Can imagine a person raiding a town and in the middle of breaking walls gain a madness level and have their shovel become questionably effective.
