Added some more essence for hight tiers enchantments and full config for non-max tiers enchants. The list is subjected to a lot of changes and balancing.
Added all loot table modification. Level 30 book is replace with item on the essence tag and random enchanted book are replaced with item on the essence tag AND in the enchantment ingredient tag, providing less hight tier drop overall.
Playable proof of concept of the mod. Need polishing and some finishing touches.
