Transmutation Tablet

The Transmutation Tablet is the workbench of Equivalent Exchange. It allows you to transmute blocks and items, allowing you to trade many low-value items for a few rarer ones, for example. You can only create items that your Tablet has already "seen", but once it has "learned" an item, it is remembered forever and you can create it at will, even if you no longer possess any of that item. At first, the interface may be confusing, but you will soon get the hang of it.

The Transmutation Tablet gives you much more control over the transmutation process compared to the Energy Condenser, and does not require you to already possess the item you desire, provided you have previously taught your tablet that item. However, the Energy Condenser is much more suitable for transmuting massive quantities of items (e.g. unwanted mining waste) into a single type of item.

The Transmutation Tablet is crafted by placing a Philosopher's Stone in the center of the crafting grid, Stone to the left and right, top and bottom and Obsidian in all four corners.

Your Philosopher's Stone will be returned to you when the Transmutation Tablet is crafted; you will not lose it.

PROTIP : If you for some reason cant access Minecraft.net, you may choose to start the game in offline mode. But by doing so, you wont have acces to your stored EMC or Recipes. All you need to do is change the name of the storage files found in your tekkit folder. Backup first before editing them in case you mess up.

C:\Users\YOURUSERNAME\AppData\Roaming\.techniclauncher\tekkit\saves\WORLDNAME\data

tablet_Player is your offline char, you will want to remove the Player part and replace it with your minecraft account name. Don't forget to reverse it when you get your internet access back!

Usage
The circle on the left of the Tablet's GUI is called the Input Matrix. When an item is placed on this circle, the EMC value of that item is displayed, and previously-learnt items of equivalent value or less will appear in the Output Matrix on the right. You may then remove items from the Output Matrix, consuming EMC in the process. Leftover EMC is stored for later use.

Multiple items can be placed in the input matrix in order to use their combined EMC. If you place a stack of items in the Input Matrix, then only the EMC of one item from the stack will be shown, but the tablet will take extra items from the stack one by one as more EMC is required.

You may place an item in the centre of the Output Matrix in order to target that item. This will cause the Output Matrix to display only items that have an EMC value equal or less than the target, with the targeted item itself showing up at the top. Use this if your Tablet is not showing the item that you desire.

The slot at the bottom, marked with a flame icon, allows you to dispose of unwanted items in exchange for EMC, which will be stored for use in transmutation.

Items and EMC left behind are stored in a Transmutation Tablet when you close it, and will be there the next time you open it. All of your Tablets share the same storage, so your items and EMC will be there even if you use a different tablet. In Multiplayer, using someone else's tablet will still bring up your tablet interface, not theirs.

Modes
The Transmutation Tablet will lock itself into either Matter or Fuel mode depending on the item placed into the input matrix. It will not allow you to transmute fuel into matter, or matter into fuel. In order to release the lock, you will need to remove all EMC from the tablet by removing items from the Output Matrix until no items are left.

The Equivalent Exchange wiki hints that there is a way to "break the lock", presumably allowing matter and fuel to be transmuted interchangeably.

You can use a Klein Star to "break the lock". Putting a Klein Star in the left side of the tablet will transfer all the EMC from the tablet into the Klein Star. Taking the Klein Star out and putting it back in will then break the Matter or Fuel lock. For instance, put an Aeternalis Fuel in the burn slot and the tablet will be charged with 8192 EMC, put a Klein Star on the left side of the tablet and that 8192 EMC will be transfered to the Klein Star. Take the Klein Star out and put it back to break the lock and use that 8192 EMC to make a diamond.

Upgrade
The tablet can be upgraded to a "portable" version, where one can select the tablet in the inventory and either RightClick or press the Extra Function key (Default ) to open the transmutation tablet interface.

Also, pressing the "Release Charge" key (Default R), you will fire a projectile. If this projectile hits a mob, the mob will randomly morph into another mob of the same type. Nether mobs will change into another nether mob, animals will turn into another animal, and overworld enemies will turn into another overworld enemy. Combine this function with eggs to create farms of any animal.

Bugs
Don't put Solar Cells, Sapphire Blocks or Obsidian pipes into the tablet, as they will disappear, without giving anything in return. In short, be careful putting anything into the tablet not listed below, you've been warned. Some items that are unrecognized by the tablet will be harmlessly put on the floor and you'll suck them back up into your inventory. However, If the item is to dissapper, It can usually be found by digging under the tablet for a while.

If you store too much EMC in the Transmutation Tablet (over 2 billion) it will overflow and become negative (you will then have to keep feeding it Matter or Fuel, whichever it's locked to). Be careful when inputting stacks of items with a high EMC.

EMC Values
Below is a list of all blocks and items that the Transmutation Tablet can learn, along with their EMC Value.

However, take note that Uranium is only transmutable in Tekkit 3.0 or later, and in Tekkit 3.1+ its EMC was reduced to 4,096 from around 49,000 EMC.
