From DragonMineZ Wiki
The optional difficulty field of a reward is an allow-set of the difficulties this reward is granted on (aliases: difficulties, difficultyType and minDifficulty). It accepts a JSON array (["NORMAL","HARD"]), a string separated by commas or spaces ("NORMAL, HARD") or a single value ("HARD"). Valid values are EASY, NORMAL and HARD. When it is left out or empty, the reward is granted on all difficulties.
