Guiding Bolt 5e 2024 vs. 2014 edition differences
Both versions deal 4d6 radiant damage on a hit, with damage increasing by 1d6 per spell slot above 1st. The 2024 version specifies "You hurl a bolt of light" and "it takes" rather than "a flash of light streaks" and "the target takes," but these are stylistic. No significant mechanical differences.
