## Gem Socketing
Arcane gems are small gems, crystals, or similar objects that imbue weapons, rings, armor or shields with additional magical effects. They make magic item selection more flexible by allowing characters to change enhancements as they advance in level and face different challenges.

Before a gem can be socketed into a socketable item it must first
be refined, cut to fit the gem socket, and imbued with magic
to reveal its innate magical properties.

#### Cutting a Gem
A gem needs to be cut into a very precise form to allow
arcane imbibement. Cutting the gem requires the use of
Jeweler's Tools. If you have proficiency with Jeweler's Tools
you can add your proficiency bonus to the check. Failing the
DC to cut the gem fractures it, making it unusable to socket,
but still valuable to sell.

| Rarity | Condition     | Skill     | DC     |
|:----|:----:|:----:|:----:|
| Very Rare  | Raw     | Dexterity     | 20     |
| Rare | Raw     | Dexterity     | 15     |
| Uncommon | Raw     | Dexterity     | 10     |

#### Imbuing a Cut Gem
A properly cut gem can be imbued with power by casting
powerful magic on it for a length of time dependant on the
rarity of the gem. The caster must spend a spell slot of the appropriate level each day for the duration as listed in the table below.  If the caster misses a day during this process, then the total duration is increased by one day.

| Rarity | Condition     | Spell Level     | Duration     |
|:----|:----:|:----:|:----:|
| Very Rare  | Cut     | 9th     | 6 weeks     |
| Rare | Cut     | 6th     | 4 weeks     |
| Uncommon | Cut     | 3rd     | 2 weeks     |

#### Socketing an Arcane Gem
Socketing or unsocketing an arcane gem requires the use of Jeweler's Tools.  Make a DC 15 Dexterity (Jeweler's Tools) check. On a success, you socket or unsocket the gem.

### Gem items

Weapons, armor, and rings capable of housing arcane gems can only be crafted by master artisans practiced in the arcane arts or working with a powerful arcane caster.

Equipment made to house arcane gems must possess equally precise indentations, requiring specialized tools and expertise in manipulating magical energy. A magical item cannot be made socketable.
