In Kingdom Come: Deliverance 2, the Post Scriptum quest presents several crucial decisions that significantly impact the outcome and rewards. If you're considering whether to help the miners, here's a detailed guide to help you navigate through this side quest.
How to Start Post Scriptum in Kingdom Come: Deliverance 2

To kick off the Post Scriptum quest, make your way to the Kuttenberg region. Once there, locate the tavern just west of Kuttenberg city along the road. Inside, you'll find an NPC named Kvyertsolav who will set you on the path of this intriguing side quest.
Write the Letter
Your first task involves assisting Kvyertsolav in writing a letter for the miners. Head to the designated house in Kuttenberg and choose the dialogue option "Justice is worth more than silver" when you enter. You'll then have the opportunity to refine the letter's content, leave it as is, or make it more aggressive. No matter your choice, the letter's outcome remains consistent.
After completing the letter, be prepared for a twist: the miners will attempt to kill you. However, you can use a Speech check to convince them to spare you.
Should You Turn the Miners Over to the Baliff?
If you successfully navigate the miners' threat, you'll face the decision to turn them over to the baliff. Doing so will immediately conclude the quest, earning you a modest reward of 100 groschen. This option, however, isn't the most rewarding or beneficial, so it's advisable to consider other paths.
Should You Help Markold or the Miners?

Your next step is to deliver the letter to Markold, the shaft owner. Speak with the bodyguard at his residence to gain access upstairs. Here, you can choose to blackmail Markold, hand over the letter, or collaborate with him against the miners. Blackmailing him is not recommended due to a challenging Speech check and the immediate end of the quest.
Opting to help Markold involves eliminating three miners, which yields a meager reward of 60 groschen and is considered the least favorable outcome.
Instead, siding with the miners is the recommended choice. Deliver the letter to Markold as planned, and he'll give you seven groschen, instructing you to meet some miners north of the city. Head to the specified location, wait for the miners, and proceed to their camp to meet Myslibor. When Markold attacks, assist the miners in defeating him. This action will conclude the quest, rewarding you with 160 groschen from Myslibor and the satisfaction of improving the miners' working conditions.
