Mystic Path Feat Save DC:

• Any time a mystic path feat requires an ability score modifier for spell attacks or saving throws, use Constitution as the modifier. The DC is calculated as 8 + your Constitution modifier + your proficiency bonus.
• If your class grants you a spellcasting feature, you can use that ability modifier for calculating spell attack rolls and the DC instead of Constitution.
