Suggestion (Required)

In contrast of your really nice revamped enchanting system, lapis has no use anymore. So, I have an idea, not very polished, but I think it comes well with the new table.

The level of each enchanting could be applied additionaly to the cost of lapis. For example:
Fire Protection I would cost 1 level and 1 lapis
Fire Protection II would cost 2 levels and 1+2 lapis
Fire Protection III would cost 3 levels and 1+2+3 lapis

and so on...

In addition to unique-level enchantments, there could be an additional config file to adjust the cost of lapis, making it 10 lapis by default (for example) or so people could decide if instead that cost could reduce it or making it even more expensive, which it would help rebalance them, plus decide the cost of modded enchantments.

Hope this could be helpful to you, I just wanted to share some ideas : )

Thanks for the suggestion!

I've had other people with similar ideas before, but i'm honestly not too sold on this. In my opinion Lapis was only tagged on to the enchanting system for the sole purpose of giving the item some more use (after all they made the lapis change in 1.8, when the enchanting system already existed for 3 years since Minecraft 1.0).

I want to keep this new enchanting system offered by the infuser as simple as possible, so adding an extra requirement involving lapis really doesn't fit too well.

I'm planning another mod though, similar to enchanting infuser, but more of a library where you don't generate enchantments just from levels, but need to provide them in some form to start with. Maybe lapis will play a role in that in some form or another.
