Gold Dragon Wyrmling

The dragon exhales gas in a 15-foot cone. Each creature in that area must succeed on a DC 13 Strength saving throw or have disadvantage on Strength-based attack rolls, Strength checks, and Strength saving throws for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Strength Saving Throw: DC 13, each creature that isn’t currently affected by this breath in a 15-foot Cone. Failure: The target has Disadvantage on Strength-based D20 Tests and subtracts 2 (1d4) from its damage rolls. It repeats the save at the end of each of its turns, ending the effect on itself on a success. After 1 minute, it succeeds automatically.
