Inspired by this thread, I'm making a cost to feed the animals: $10/day for SM 0. I do things a day instead of a week to handle a game calendar. So for the pony and the saddle horse, both of which are SM +1, the cost is $20 each a day.
So, Cost of Living: $20 Ash, Ash's horse, Kôštē, Mayhem, Caleb, ponies
$22: Xórin (Compulsive Carousing)
$24: Kim (Compulsive Spending)
$186 day, $1,302 week
I suppose we could call it an even $1,300, so long as Xórin and Kim are the ones who suffer.
