Xenoblade Chronicles Gem CraftingSource: Nintendo

When going into battle in any RPG your characters' equipment can make all the difference, and Xenoblade Chronicles is no exception. Shulk and his allies will have a number of weapons, armor, and accessories to choose from throughout the course of the game, but some of these pieces of equipment can be customized with Gems to make your team even stronger. With just shy of 100 different types of Gems in varying strengths, figuring out which Gems to use when can be tricky. Fortunately, we here at iMore have everything you need to know about using Gems!

What are Gems?

Gems are condensed and refined Ether - the crystalized life force found in all living things. Each Gem provides some sort of stat boost or protection to the hero using it. Some Gems will provide a flat stat boost, like a Strength Up Gem, while others might enhance your attacks, like a Lightning Attack Gem. Gems can be acquired in a number of ways, including:

VPN Deals: Lifetime license for $16, monthly plans at $1 & more

  • Completing quests - there are nearly 500 quests given to the party by the named NPCs around Bionis and many reward you with Gems.
  • Trade with NPCs - many of the nearly 200 named NPCs will trade gems.
  • Completing sections of the Collectopaedia - by finding one of each type of item in the sections of the Collectopaedia, you will earn a weapon, a piece of armour, or a Gem.
  • Crafting - once the Gem Man has fixed the Gem Forge, you can use Ether Crystals and Cylinders to craft your own Gems.

Gems are classified into six different categories, based on their effects, and ranked I-VI. Each Gem also has an element (Fire, Earth, Wind, Water, Electric, or Ice) which determines the sort of Ether Crystals used to craft them. Although Gems can be sold, the amount they sell for is not worth the effort of farming them, so it's best just to put them to good use in your equipment and only sell low rank Gems you won't be using anymore to free up space in your inventory.
