I'm having a problem finding where the rules set what stat controls the DC for the Deflect Attack reaction. Beyond has it set by Wisdom. Which is fine, I suppose, but I would like to see in the rules how to determine the DC number. If I'm overlooking something obvious, sorry but let me know :)

Monk Class Features->Monk's Focus:

Some features that use Focus Points require your target to make a saving throw. The save DC equals 8 plus your Wisdom modifier and Proficiency Bonus.

Thank you. I completely missed that paragraph!
