XP Ore

XP Ore is a mod that adds a set of the titular ores which are intended to be set up in a way which provides an alternative to mob-based XP farms and encourages automation.
The mod creates up to 10 different tiers of XP Ore, a block which simply gives XP when mined and reverts to a drained variant. The higher the tier, the more XP you get.
The interest comes from the intention that pack devs can add recipes to turn the Drained XP Ore back into XP Ore (at any tier) by combining it with automatable materials; the more complex the automation of the ingredients, the higher the tier of ore.
With an auto-placer, the player could create a fully automatic XP farm, with the caveat that they must incorporate the automation of the transformative ingredients and the reinvigorative crafting itself.

What this mod is (currently) not
This mod has no worldgen. This is not an ore in the conventional sense but merely in the way its behavious mirrors similar ores like Quartz.
This mod has no recipes. The nature of my intent for this mod is that it is very pack-specific. I may consider adding a vanilla default configuration including recipes.
This mod is not useful without configuration. There is no way as-is to obtain the XP Ore.

Configuration
There are currently three config options:
- The number of different tiers of ore the mod adds. The mod can add anything from 1 (or even 0, for whatever reason) tier of XP Ore to up to 10 different tiers.
- The starting value of XP gain; this is the amount of XP you get from a Tier 1 XP Ore
- The amount of XP each tier increases the amount by. If the starting value is A and this value is B, the Nth tier of ore gives A + B(N - 1) XP.

As always, all suggestions are welcome.
