Almost every aspect of HxC-Enchants Mod 1.7.10, 1.7.2 is configurable. from the rarity of the enchants to the max levels and if enabled or not. My core extends the enchant array to 512 so you can set enchant IDs much further.

Air Strider Enchant only works in Single Player for now and the other disabled ones don't work just yet so don't touch else waste of xp or possible crash.
