Gunslinger 5e Misfire

[DungeonDwellers]

Hey Everyone,

Very new here. I am trying to run a campaign with Matt Mercer's Gunslinger class. I would love to automate the misfire and see if anyone has found a way to make that possible? or is it just a lost hope?

Welcome to FG.

I don't know this class so you'd need to give us some insight into what misfire is. (I can guess - but then I could get it wrong)

Misfire is a field specific to firearms.
If the attack roll is equal to or below the misfire threshold the gun needs attention and cannot be used until a repair attempt is made. If the repair attempt fails, the firearm will require mending: as in downtime action taken to repair it.
The threshold so far seems to be between 1 and 3 but nothing can prevent a DM from changing the said value to a higher number to translate the nature of an experimental firearm.

My understanding of the application tells me a custom extension may be required to properly handle this. But I would like to be told otherwise since I was just asked to implement the very same sub-class by one of my players.
