What do you roll when casting spells?

When casting spells, you typically roll a d20 and add your Proficiency Bonus and Spellcasting Ability Modifier to determine the outcome, with the goal of meeting or exceeding the Spell Level and DC (Difficulty Class) required for the spell to succeed. The specific roll and modifiers used can vary depending on the type of spell being cast, such as attack spells or saves, but the core principle of rolling a d20 and adding relevant modifiers remains the same.

Spellcasting Check
