Pathfinder calculating save DC for Dread Wraith Sovereign

[g3taso]

Here's the pathfinder open-content Dread Wraith Sovereign template (http://www.d20pfsrd.com/bestiary/monster-listings/templates/dread-wraith-sovereign-cr-3), and the section that I have a question on is the Constitution Drain:
"A dread wraith sovereign's incorporeal touch attack deals 1d8 points of Constitution drain unless the creature struck succeeds on a Fortitude save. The save DC is Charisma-based."

How is the save DC calculated? Just 10+Attrib (charisma, in this case)? Or are there bonuses like spell levels?

10+1/2 HD + Cha Mod, usually.

10+1/2+Cha mod is assumed for a Cha based Supernatural. It's an important rule of thumb. :smallsmile:
