Liquid XP
This mod introduces liquid experience (Liquid XP) and specialized machinery for working with it. Full usage requires a mod capable of transporting liquids, such as Buildcraft, Thermal Expansion, or RedPower 2.
One bucket of liquid XP is equivalent to 10 experience points. For comparison: each level up to 15 requires 17 experience points.
LXP Absorber
When this block is placed in the world, standing on it converts your experience into liquid, which accumulates in its internal buffer and is automatically transferred to nearby blocks that can accept it (e.g., pipes, liquiducts, and Buildcraft tanks). This does not require wooden pipes or redstone-powered liquiducts.
You may notice that a small amount of experience remains unabsorbed—this is due to rounding, as Minecraft tracks experience in a complex way.
To obtain buckets of LXP, use any filling method (right-click on a Buildcraft tank with a bucket or use a Thermal Expansion liquid transposer).
LXP Collector
This block functions similarly to the absorber but instead of taking experience from players, it collects experience orbs in a 13×13×13 area around itself (6 blocks in each direction).
However, this is not enough to create an automatic experience farm. As known, mobs drop experience (and rare items) only if killed by a player, more precisely—if they die within 3 seconds of taking damage from a player.
LXP Catalyzer
For a relatively small cost in liquid XP (can be pumped in from any side), this block causes nearby mob deaths to count as player kills. The cost is 1 experience point per mob. The range is the same as the collector, and any mob killed within this area will drop experience. If a mob leaves the area, it will drop experience only if it dies within the next 3 seconds.
LXP Imprinter
This block requires blank medallions as input and charges them with LXP to a certain level, which can be configured in the interface.
Blank medallions can be placed on the left in the interface or supplied from the top. Charged medallions are extracted from the right or the bottom of the block. LXP can be pumped in from any side.
LXP Enchanter
It requires charged medallions (top) and books (left). LXP is not needed. When a charged medallion and a book are both present, it enchants the book using the levels from the medallion, returning an enchanted book (right) and a blank medallion (bottom). There is a config option to allow enchanting items other than books—disabled by default. Unlike the standard enchanting table, this block can store multiple enchantments in one book.
The slot in the lower left corner of the interface is the "template slot." If empty, any enchantments can be stored in the book, as with normal enchanting. Otherwise, any enchantable item can be placed here to determine available enchantments. For example, using a golden sword as a template with level 30 medallions, the enchanter will create enchantments as if enchanting a gold sword at level 30 but place them on the book instead of the sword.
The template item takes 4 "uses" of damage for each level used in the enchanting process. In the example above, the golden sword will receive 120 damage points and be consumed after each enchantment, as it only lasts for 33 uses. A diamond sword would also receive 120 damage points but last for 13 enchanting operations and yield less valuable enchantments due to lower enchantability (as in vanilla).
New template items can be inserted from the back of the block. If a non-enchantable item is used as a template, the enchanter will not function.
The enchanter requires bookshelves placed around it. Starting from version 54.0.1, bookshelves can be up to 3 blocks away horizontally and up to 2 blocks above or 1 block below the enchanter. Horizontal cross-section of this area:
Vertical cross-section:
The block does not check for obstructions, so other machinery can be placed between the enchanter and the bookshelves.
Due to the enchanter's reduced cognitive capacity compared to a human, it requires significantly more bookshelves than a manual enchanting table. Two bookshelves are needed per medallion level. To use medallions up to level 30, 60 bookshelves are required.
LXP Combiner
Essentially, this is an LXP-powered anvil. It can perform all functions of the vanilla anvil except renaming. It cannot apply enchantments to "wrong" items—e.g., it won't put Protection on a sword or Sharpness on a dirt block.
It is not capped at level 40. It does not use the vanilla mechanic where already-repaired items cost more to repair again. This works both ways: items already repaired in an anvil can be used as input with no extra cost, and the resulting item can be repaired in an anvil without additional cost.
Input is from the left and right sides of the block. Output can be extracted from the bottom. LXP can be pumped in from any side.
There is no LXP machine for renaming items.
LXP Isolator
This block, added in version 55.1.0, is a machine that separates enchantments from items. Place an enchanted tool/weapon/armor piece/book on the left, empty books below it, and supply a relatively small amount of LXP.
For automation, insert items from the top and extract them from the bottom. Books can be inserted from any side. This layout is compatible with hoppers.
If the input item has no enchantments or is damaged, it moves directly to the output slot at no cost.
Otherwise, 15 experience points (1.5 buckets) are consumed, and the first enchantment is removed from the item and transferred to a book—unless the item was already a book with one enchantment, in which case it moves to the output slot at no cost.
