This is kind of a special request.

Lets say that I set on all "Hoe's" -90 % Attack Speed, then the Cooldown will not be updated. ->pic
I think this would be the same when the player has any potion effects that change Attack Speed in some kind (Bauble Rings or other).

Personal goal:

• I want tools to be used as weapons
• I will change the Attack Speed of all Tools to 1.6 and enhance damage
• I will use the MOD: Set Bonus to achieve that, but it can not display the true attack speed... so I cam here after testing your mod -> https://www.curseforge.com/minecraft/mc-mods/set-bonus
