Rare Enchantments? And other confusing issues

[anticode-403]

So, I've been messing around with this mod and various enchantments for it for a while now and there are a lot of very unclear decisions. I discovered that the mod takes rarity into account when rolling enchantments, and it seems like (based on what I can tell from editing files) that enchantment rarity is indicated by the border around the enchantment? But, I've been COMPLETELY unable to get certain enchantments, like Prot and Sharp, seemingly randomly whenever I modify the config. I assume these are rare because of the red border they have, but its, again, exceptionally unclear.

This is a really bad issue, but between the lack of proper documentation, the innate randomness of the mod, the fact that I've never played MCD before, and that there's no explanation as to the exact minutiae of how the system works anywhere that I can find I'm really not sure how I can create a better issue.

I only realized the difference between how Echo Shards and Lapis Lazuli worked because of another issue that was raised previously.

So, in that spirit, can you clarify some of this for me?

Some enchantments are locked behind advancements. There is unlocks option that locks certain enchantments behind advancements. Namely, it locks the "powerful" enchantments (such as prot, eff and sharp) behind the end advancement in the default configuration.

Regarding the documentation, it is a known issue.
