Wall of Fire 5.5e 2024 vs. 5e 2014 edition differences

The 2024 version states "up to 1 minute" duration, indicating potential for shorter duration, while the 2014 version states "1 minute" with no variability. The damage increase wording changes from "when you cast" to "the damage increases," but mechanics remain the same. No other significant mechanical differences.
