How to Use Uncut Gems

Uncut Skill Gems create active skills, Uncut Support Gems create modifiers that socket into a skill, and Uncut Spirit Gems create Persistent skills that usually reserve Spirit. These three item families are not interchangeable.

• Use Skill for an active attack, spell, minion, or other active skill.
• Use Support for a modifier placed under another skill.
• Use Spirit for a Persistent skill that is enabled in the Skills Panel.

Right-click the Uncut Gem to open Gemcutting, then choose a compatible entry. The list is grouped by category and the character's associated category appears first, but the Gemcutting directory should be used to compare the complete selection. A Skill becomes available when the Uncut Skill Gem level meets or exceeds that Skill's Gemcutting tier.

• Use the category tabs or search to find the intended gem.
• Read the exact gem card before confirming.
• Confirm the resulting level or support tier shown by the Uncut Gem.

A higher-level Uncut Skill Gem can raise an existing active Skill Gem to that Uncut Gem's level. Use an Uncut Spirit Gem for an existing Persistent Skill Gem. The upgrade sets the target to the stated level, so do not spend a lower or equal level Uncut Gem expecting an additional level. Support Gems use tiers instead: engrave the required tier and replace the lower-tier Support when the new version is appropriate.

• Match Skill with Skill or Spirit with Spirit.
• Check the existing gem level before spending the Uncut Gem.
• Treat Support tiers separately from active Skill levels.

Open the Skills Panel and place a Support Gem into a Support socket under the Skill it should modify. The Support must be compatible with that Skill. A normal Skill begins with two Support sockets and eligible Skill Gems can reach five with Jeweller's Orbs. The Support Finder can show explicit compatibility before a Support is engraved.

• Select the Skill that should receive the Support.
• Use a free Support socket under that Skill.
• Check compatibility and the Support's Attribute requirement.

Assign an active Skill to an input before using it. Enable a Persistent Skill in the Skills Panel and make sure enough Spirit remains available for its reservation. Since update 0.3.0, an unmet Attribute requirement on a Support disables that Support rather than the entire Skill. The same update removed the one-copy-per-character Support restriction.

• Assign active Skills to an input.
• Toggle Persistent Skills on and leave enough unreserved Spirit.
• Meet each socketed Support's Strength, Dexterity, or Intelligence requirement.
