Gem (XC1)

Gems are items in Xenoblade Chronicles and Future Connected that can be attached to s and to provide certain advantages, such as raising the user's stats or providing resistance against a specific debuff.
Gems are available in two forms: loose and permanent. Loose gems can be placed into weapons and equipment with open gem slots at will, while permanent gems are affixed to specific weapons or equipment and cannot be removed or exchanged. Weapons can have up to three gem slots, while equipment can have only one, and either may have none at all - as a result, the most gems that can be equipped by a character at once is eight. Some gems can be placed into both weapons and armour, but many attack-boosting gems are only allowed in weapons, and many defence-boosting gems are only allowed in equipment; permanently-attached gems are not subject to these restrictions.
Equipping two gems of the same type will add their effects together. However there is an upper limit, specific to each type, beyond which adding additional gems of this type has no effect.
==Sources==
Gems can be acquired in a few ways:
* Gem crafting - a process in which ether crystals are machined into new gems.
* Trading - Many s offer gems in trade. Gems received are of a certain rank, but with a random strength within that rank.
* s - Many quests have gems as a reward, often of a predetermined rank and value.
* - Gems are the most common reward for completing a row in the Collectopaedia.
* s - Many High Entia or Giants' chests contain gems.
* In the , gems can be traded from the in exchange for .
* In Future Connected, gems can be obtained directly from ether deposits without having to refine its crystals.
===Crystals===
Ether crystals are the raw material used to craft gems. They can obtained from two main sources: found in silver and gold chests dropped by enemies, and mined from crystal deposits across the Bionis and Mechonis. Enemy crystals can have the properties of one or two gems, specific to the enemy they came from. Mined crystals can have between one and four gem properties, all of which must be the same colour. In either case, gem crafting is used to separate and combine these properties to produce gems.
Certain enemies and mining spots produce ether cylinders instead of crystals. Gem crafting also creates cylinders out of incomplete gems, so progress can be saved for later. Cylinders are identical in functionality to crystals, though they tend to only have a single gem property.
==Rank==
Gems come in six ranks, with rank being the weakest and cheapest, and rank being the most powerful and most valuable. The potential strength of a gem's effect is restricted by its value; for example, can only have a value between 5 and 10 (inclusive), while a Strength Up can be from 35 to 40.
Crystals come in mostly the same ranks as gems. No rank crystals exist, but gem crafting can produce gems of one rank above the crystals involved.
Each type of gem has its own base selling price, which is modified by its rank. Crystals sell for 0.3x the price of the matching gem; a mixed crystal sells for the sum of its components.
Rank	Sell price	Crystal name
 	1.0x 	Small
 	1.2x 	Large
 	1.5x 	Pretty
 	1.8x 	Bright
 	2.0x 	Rare
 	2.5x 	—
==List of gems==
Gems come in six elements: fire, water, electric, ice, wind, and earth. The element of a gem is loosely related to its properties, and mostly controls what sorts of ether crystal deposits the corresponding crystal can be mined from.
* Fire gems tend to raise physical offenses, resist lethergic debuffs, and boost emotionally-charged mechanics.
* Water gems tend to boost , resist physical debuffs, and provide additional sources of healing.
* Electric gems tend to raise ether offence, boost situational physical offenses, and amplify the status.
* Ice gems tend to resist mental debuffs, inflict lethargic debuffs, and reduce .
* Wind gems tend to raise , resist disabling debuffs, and amplify the status.
* Earth gems tend to resist physical , amplify weapon damage, and manipulate ing and .
