This guide will help you to prepare your team for the Harvest. It includes trinkets, skills, quirks and items. The guide does not claim to be the best possible, there is still a lot of space for improvements.
The Harvest run, which ended up with 1000 slaughtered monsters and 1470 collected shards. Here is my party/quirks/trinkets list, which may help you to prepare your party for a long run. It does not include the walkhrough.

Also take all possible food, herbs, holy water, laudanum, antivenom, bandages. You may also take keys (optional) to open the loker. Also take a heroe’s ring for virtue bonus and give it to proper characters when they need it. I also recommend to visit Harvest during Valiant spirit event for more virtue bonus.
During the weald season, try to catch rabies for your heroes from wild dogs. Especially for Jester and Highwayman. You will get + 15 damage and -10 accuracy. But accuracy debuff can be nullified by Battle ballad.
