Saving Throw Difficulty Class
A saving throw against your spell has a DC of 10 + the level of the spell + your bonus for the relevant ability (Intelligence for a wizard, Charisma for a sorcerer or bard, or Wisdom for a cleric, druid, paladin, or ranger). A spell’s level can vary depending on your class. Always use the spell level applicable to your class.
DC = 10 + spell level + ability modifer + mods
