Zachariah worked on the island for a long time and eventually decided to make a weapon that was unique to his skill sets and could be used quickly when the lab subjects acted up. This is his revolver. Unlike his shotgun, this releases an electrical shock once the bullet lodged in its target.
If your target is immune to lightning damage then it will take the same amount of damage but in piercing instead of lightning.
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.
This weapon has the following mastery property. To use this property, you must have a feature that lets you use it.
Sap. If you hit a creature with this weapon, that creature has Disadvantage on its next attack roll before the start of your next turn.
Notes: Damage: Lightning, Range, Ammunition (Firearms), Reload, Sap
