Calculating Spell Save DC, or Difficulty Class, is a crucial aspect of Dungeons & Dragons and other tabletop role-playing games. It determines the difficulty of saving throws against spells cast by players or non-player characters.
The Spell Save DC is typically calculated using the following formula: 8 + proficiency bonus + relevant ability modifier. The proficiency bonus is determined by the character’s level, while the relevant ability modifier is based on the spellcasting ability used (Intelligence for wizards, Wisdom for clerics, etc.).
