Gem Socketing

Socketed items have open slots that can be filled with gems to add permanent item properties. Items with available sockets will have a number in parenthesis in the name of the item.

Socket Types

There are two categories of sockets:

Type	Used on
Weapon socket	Weapons, staves, and ammo pouches
Gear socket	Armor, shields, helms, jewelry, cloaks

A gem must match the socket type — weapon gems go in weapon sockets, gear gems go in gear sockets.

Gems Are Also Gated by the Kind of Item

Matching the socket type is not enough on its own. Each gem's property also has to make sense on the item you are setting it into, and the game refuses the ones that do not ("That gem will not hold in a ranged weapon!"). The gem is not consumed when it is refused.

The main restrictions on weapons:

Gem	Melee	Ranged (bows, crossbows, slings)	Thrown	Gloves	Ammo
Damage Bonus (any type)	yes	no	yes	yes	yes
Enhancement Bonus	yes	yes	yes	no	yes
Attack Bonus	yes	yes	yes	yes	no
Keen	yes	yes	no	no	no
Mighty	no	yes	no	no	no
Massive Criticals	no	yes	no	no	no
Vampiric Regeneration	yes	no	yes	no	yes
Extra Ranged Damage	no	yes	no	no	no

Ranged weapons get their damage from Mighty, Massive Criticals and Extra Ranged Damage rather than from damage gems; put damage gems on the ammunition instead.

An ammo pouch counts as the ammunition it produces, not as a bag — a quiver takes the gems an arrow would take, an axe sling the gems a throwing axe would take.

Gear gems are gated the same way — Freedom of Movement, Haste, Improved Evasion, Regeneration and the elemental resistances will not go into a shield, for example, and most gear gems will not go into a magic staff.

Identifying Socketed Items

Socketed items show their current gem contents in their description. Open the item description to see how many slots are filled and what properties each gem provides.

Socket Gems

Gems are found in loot and can have many properties. Gems can be stored and combined in the Gem Bank which is an option in the PC Wand. You can also use gems on gems of equal property and value to increase the value. For example, a +1 AC gem and another +1 AC gem can be combined to make +2 AC. You just use the item on the other item of equal value.

Gear Gem Properties

Gems can add properties including (but not limited to):

Property	Notes
AC	Armor class bonus
Enhancement/Attack bonus
Ability bonus	STR, DEX, CON, INT, WIS, or CHA
Regeneration	HP per tick
Freedom of Movement	Immunity to slow and entangle
Improved Evasion
Haste
Darkvision
True Seeing
Damage Resistance	Slashing, piercing, bludgeoning, or elemental
Damage Immunity	Physical damage types
