Blackpowder Inquisition

[Arryn Raven]

In the description for this Inquisition it says:

When you hit an arcane spellcaster or a creature that uses spell-like abilities with a firearm attack, that creature must succeed at a Fortitude saving throw. If the spellcaster fails, he takes a –4 penalty on concentration checks for 1 round.

So my queston is: What's the DC for the Fort save?

Inquisitions: "If an inquisition's granted power calls for a saving throw, the DC of the save is equal to 10 + 1/2 the inquisitor's level + the inquisitor's Wisdom modifier."
