Is it intentional that there's no Rest Sites after the Path of Chaos or am I just being very unlucky not to have found one over 30 levels later?
By this do you mean after beating the Path of Chaos? If so, I don't think there is, I could add one though.
I don't mean directly after, I mean at all. Do Rest Sites exist in the Overworld after the Path of Chaos?******
Thinking about potential new buildings as you seem to have made space for MANY of them in The Sanctum.
Clockmaker.
Collect clocks or clock fragments.
Each clock can move forward the idle time of any one building by x time.
Kennels.
Much like the Soul Storage but for pets and boosted using food from expansion or bought from the kennels.
One boosted animal would boost all instances of that same animal.
Bar/Pub/Nightclub/Social Hall
Every soul would be here at one time or another, but buying drinks or food for any of them would increase the chance of that particular one being selected by the Soul Creator.
Clothing store.
Shoes - speed.
Raincoat - water resistance.
Scarf - freeze resistance.
etc.
Not a cosmectic change.
Per character.
x% chance of activation per item OR permanent passive increase.
x of each item can be bought.
Cred/XP/Magic as currency so the player can spend whatever they have excess of.
Cafe
Consumable food items which can be used in battle for varied effects.
Tree
A massive tree that grows random items and has to be checked now and then. It could be boosted to grow better items or be truly random. It could grow any item at all including the ones mentioned above and...
...HAMMERS!!!
Just a few things that come to mind that would work.
