two new enchantments

so I got an idea for new enchantments, the first one called keeping, basicly when a tool is enchanted with the enchantment it will sort of be keep inventory, but only for the enchanted tool specificly, so if you fall in lava for example the tool will still be in the same slot when you respawn, but it will be incompateble with mending...

the second one is called curse of breaking, this one will have 2 levels, curse of breaking 1 will take double the durability for every action, for example if you have a sword with this enchantment and you hit a mob, that usually takes 1 durability, but with curse of breaking 1 it will take 2 durability enstead, and the curse of breaking 2 it will take 4 durability enstead, also, even if you have unbreaking 3 on the tool it will cansel out the effects of the unbreaking enchantment, these 2 enchantments will be able to be on any thing that is enchanteble...
