Item-Modding

By using the anvil brick, you can modify items by repairing them if degraded, by applying modifiers to them or by combining certain items together to form new ones. When an item can be successfully modified, a "ghost item" will appear in the anvil's output slot.

Repairing Items
By inserting a Restore Hammer in the anvil's "tool slot" (the one with a hammer icon), and then placing another item in the "input slot" (bottom-left of the GUI), you can then repair that item to full durability after selecting the "Modify" button.

Note: If an item's full durability is increased (mentioned in detail below), the item will be restored to the modified / increased durability instead.

Applying Modifiers
The various gems included with RPGx allow you to add modifiers, such as for increasing an item's durability or reducing it's weight. Effects can also be added onto projectile-based weapons (like the bow), such as kick, burn and freeze effects.

To apply a modifier, insert a Mod Hammer in the tool slot, and the item you want to mod in the input slot. Then, add one of the colored gem items in the "mod slot" - marked with a plus (+) sign. Select "Modify" and the item will be altered; the gem itself will be removed. The effect of each gem is listed blow: Note: Modifiers can be added multiple times to the same item, increasing it's effect. The kick, burn and freeze effects can only be added 5 times / up to "level" 5.
 * Amethyst ( Purple ) - Reduces an item's weight by 5 units.
 * Diamond ( Clear ) - Increases an item's durability / health by 10 units.
 * Emerald ( Green ) - Increases effect probability (how likely a kick, burn or freeze effect will be added to a player who the projectile collides with) by 5%. Probability defaults to 30% for all items.
 * Onyx ( Black ) - Applies a "Kick" effect, which knocks a player backwards.
 * Ruby ( Red ) - Applies a "Burn" effect, which causes a player to catch on fire for a certain amount of time (and reduces their health, based on the level of the effect).
 * Sapphire ( Blue ) - Applies a "Freeze" effect, which prevents a player from being able to move for a certain amount of time (in seconds, based on the effect's level).
 * Topaz ( Yellow ) - Increases an item's efficiency / effectiveness (for now mainly used for the axe and pickaxe) by 5%. Efficiency by default for all items is 30%.

Combining Items
Using the Blacksmith Hammer in the anvil's tool slot will allow you to combine certain items together to form new items. Examples of combinations are listed below: Note: If both Item Durability and Degrade Items On Use are enabled, tools used in the anvil's tool slot will degrade every time you modify an item.
 * Iron Ingot ( input slot ) + Iron Ingot ( mod slot ) = Steel ingot.
 * Iron Ingot ( input slot ) + any tool part blueprint ( mod slot ) = tool part item.
 * Steel Ingot ( input slot ) + any weapon part blueprint ( mod slot ) = weapon part item.
