In the 1.8 version of Dynamic Difficulty you're able to add execute commands upon entering/ leaving a DD difficulty and able to set a maximum affinity gain and loss per minute (Thanks to elteammate). There is a new /dd me command to see your own DD difficulty, able to add extra damage per armor point a player has and TONS of new bugs have been found and fixed.

Sorry everyone that was affected by the netherite armor bug and I hope you have a nice day!
