Air Domain's Turn Partially Bugged

[How to Disappear]

Compared to what the wiki says about the Turn Ability:

Flurry: Nearby enemies in a huge radius roll a fortitude save VS DC 10 + 2*CHA or are knocked over for 1d4 rounds.

A cleric with 12 charisma should have a DC of 12 when flurry is activated. It is, instead, a DC of 8.



Even improving charisma to 15 only sets the DC to 10
