This +2 greater striking flintlock pistol has the odd construction of possessing two triggers, one of soapstone and one of onyx, clearly separated with individual trigger guards. Originally created by a student at Blythir College in Alkenstar, the mountebank's passage has the ability to create temporary linked portals on existing surfaces. The weapon disappeared shortly after its invention, but rumors have circulated that it now belongs to a group of thieves who use it to commit impossible robberies.

Interact
Requirements the mountebank's passage isn't loaded
Effect You pull the soapstone trigger. Choose a vertical surface within 120 feet. A beam of white energy crackles to the vertical surface and creates a white portal on that surface. Any creature who moves through the white portal comes out through the mountebank's passage's black portal, if one exists on the same plane. Using this activation causes any previous white portal to disappear, even if you don't create a new portal; otherwise, the portal lasts until your next daily preparations.

Traits
A rules element with this trait is one-of-a-kind. The DC of Recall Knowledge checks related to creatures with this trait is increased by 10.
ConcussiveThese weapons smash as much as puncture. When determining a creature's resistance or immunity to damage from this weapon, use the weaker of the target's resistance or immunity to piercing or to bludgeoning. For instance, if the creature were immune to piercing and had no resistance or immunity to bludgeoning damage, it would take full damage from a concussive weapon. Resistance or immunity to all physical damage, or all damage, applies as normal.
ConjurationEffects and magic items with this trait are associated with the conjuration school of magic, typically involving summoning, creation, teleportation, or moving things from place to place.
FatalThe fatal trait includes a die size. On a critical hit, the weapon's damage die increases to that die size instead of the normal die size, and the weapon adds one additional damage die of the listed size.
