Having almost finished reading through the core portion of the adventure and working on chapters 5-8, I still have not seen anywhere where in the book it indicates which class(es) can have proficiency with Pistols, or how a character can obtain proficiency with the weapon (Downtime?).
The Content Catalog confirms that Pistols and Smokepowder can be unlocked and purchased.
However, there is nothing to advise about how to acquire proficiency with the weapon. Any updates I have not seen officially on this?
Also, what if a character is not proficient in Smith's tools? What would be the cost to have bullets made?
Any help or direction to official resources would be appreciated.
The rules in the DMG for firearms proficiency are the following: p267
"PROFICIENCY It's up to you to decide whether a character has proficiency with a firearm. Characters in most D&D worlds wouldn't have such proficiency. During their downtime, characters can use the training rules in the Player 's Handbook to acquire proficiency, assuming that they have enough ammunition to keep the weapons working while mastering their use."
Once you have achieved proficiency they are listed under Ranged Martial Weapons on p268. If someone said "use the rules in the DMG" then the citation on proficiency is above and I would think some clarification would be needed if they meant something else.
If smokepowder is set on fire, dropped, or otherwise handled roughly, it explodes and deals fire damage to each creature or object within 20 feet of it: 1d6 for a packet, 9d6 for a keg. A successful DC 12 Dexterity saving throw halves the damage.
Casting dispel magic on smokepowder renders it permanently inert.
