Augment Slot

Overview
Augment Slot is a gem socket on certain named or random items. By adding an augment into a slot, your item gains an additional effect, as long as the augment is slotted. This crafting system introduced in Update 17 replaced the two older augment systems - Epic Augments, and Guild Augments (both older systems can still be used on legacy items that no longer drop in game).

Color types
Augment Slots appear in one of seven different colors:

Random treasure
5% of generated items have an Augment Slot. When found on a lootgen (random) item, the augment slot replaces some of the enhancement value/base price modifier that the item would have had otherwise, such as Enhancement Bonus, prefix, or suffix.


 * Colorless Augment Slots take +1 of the item’s total enhancement value.
 * Red, Blue, and Yellow Augment Slots take +2 of the item’s total enhancement value.
 * Green slots available on random accessories as of Update 19. They have an enhancement value of +3.
 * Random accessories with 2 slots (Yellow and Colorless) can be found since Update 19.
 * Purple and Orange slots cannot yet be found on random treasure. They are found on named treasure only.

Named items
Augment slots have been added to many of new/upgraded named items, see Update 17 named items for details.

Compatibility with Cannith Crafting
Augments and Augment Slots are compatible with Cannith Crafting. Augment Slots and slotted augments persist through disjunction.

When on a Craftable item,
 * a Colorless Augment Slot adds +1 to the item’s total enhancement value.
 * Red, Blue and Yellow slots add +2 to the item’s total enhancement value. For example, a Greater Spell Focus (+6 effect) shield of Superior Stability (+6 effect) with a Red slot (+2 effect) requires at least +14 potential.
 * Green Augment Slots (and purple or orange, if at some point they are available on an item which can be made Craftable) add +3 to the item’s total enhancement value.

Augments
Augments are a kind of miscellaneous items, they do what Augment Crystals used to do before and more. However, the benefit bestowed by an augment will typically be at a higher minimum level that the normal item enchantment.


 * Unbound augments can be found in treasure chests (need source and verification on this info):
 * Level 1-7 chests have a 5% chance per player of containing an augment gem.
 * Level 8-16 chests have a 2% chance per player of containing an augment gem.
 * Level 17-25 chests have a 1% chance per player of containing an augment gem.
 * Lahar the Epic Trader in the Twelve sells some augments. Their costs in Epic Dungeon and Epic Raid tokens are lower than their previous costs.
 * Level 12, 16, 20, and 24 Augments will be found in the Ruins of Gianthold in exchange for Ancient Elven, Giant, and Dragon relics, and the restored versions thereof. Level 24 augments cost additionally Commendations of Heroism.
 * Update 17 also introduces the first three “Named” Augments, which drop in specific locations inside certain quests. Named Augments can do special and wondrous things. See the list of Named Augments here.
 * Update 17 Patch 1 changes Collectable turn-ins to provide level 1, 4, and 8 Augments for collectables or Astral Shards.
 * Some Augments are also sold in the DDO Store (bound to account).
 * Update 19 added skill augments and higher level versions of previous augments. All of which have a chance of appearing in any appropriate level quest.

Augments can be stored in an Augment Bag (available only from the DDO Store).

Usage
To use an Augment, double-click on it from your inventory. Then, a barter-shop style window specific to that augment will appear on screen.

Place the item you want to augment (which needs to have an appropriate slot), select the slot to place the augment in, and hit the “Augment!” button. (You need to select the recipe even if there’s only one slot available.), then your item gains that Augment's effect.

At any point, you can replace the augment you have slotted by placing a new one in the same slot. This way however, new augments overwrite old augments, and you don’t get the old augment back. Alternatively, you can use Jeweler's Tool Kit (DDO Store only or a VERY rare grab in Daily Dice) to unslot an augment and claim old augment back. It is also possible to take augment off from pre-slotted named items using it. 

Every augment has an associated level requirement to use it. The common (non-named) augments move up in increments of 4 levels at a time: 4, 8, 12, 16, 20, and 24. Slotting any augment also increases the slotted item’s minimum level to the level of the slotted augment for as long as that augment is slotted, unless the item’s minimum level is already equal or higher.

Available Standard Augments
The below listed Augments are implemented with the introduction of the Augment system.

Please note the following:
 * Most augment bonuses, unless otherwise specified, are an Enhancement Bonus.
 * Spell Power Augments are an Equipment Bonus.
 * Named Augments are not on the list below; see this list.

New Augments will continue to be added in future updates. For example: Colorless augments that provide bonuses to Skills (Enhancement or Competence?) are currently planned as a future update to this system.

Also, some of these are chest drop only and not purchasable at vendors in game. See the full list of purchasable ones and proper name of the Augments here.

Purchasable Augments
Some augments can be purchased from vendors and collectors in Gianthold and Stormreach.


 * Lahar in The Twelve sells augments for 20 Tokens of the Twelve.
 * Collectors throughout Stormreach will give you a semi-random augment if you turn over enough Collectables or you can choose a specific augment if you pay with Astral Shards.
 * Vendors in Gianthold will trade augments for Relics (and Commendations of Heroism).

For a full list of who sells what see the Purchasable Augments page.

Ruby Eye Augments
Update 21 (Released on March 10th, 2014) introduced six new augments called Ruby Eye Augments. These augments have no minimum level, and have their benefits scale based on the minimum level of the item. This allows a character to equip the Ruby at whatever level is desired, and continue to slot the augment on future items as the character levels up while increasing the overall benefit of the augment. All six augments have a 2% chance to provide a related damage type as an AOE effect. The six Ruby Eye Augments augments are:


 * Ruby Eye of Erosion: 2% Chance On-Hit to cause a blast of acid that deals 3 to 18 points of acid damage per Minimum Level of the upgraded weapon to all nearby enemies. (So, a ML 4 item slotted with the augment would have a 2% chance to do 12 to 72 area of effect damage to all nearby enemies.)
 * Ruby Eye of the Inferno: 2% Chance On-Hit to cause a blast of flame that deals 4 to 16 points of fire damage per minimum level of the upgraded weapon to all nearby enemies.
 * Ruby Eye of the Glacier: 2% Chance On-Hit to cause a blast of cold that deals 7 to 14 points of cold damage per minimum level of the upgraded weapon to all nearby enemies.
 * Ruby Eye of the Tempest: 2% Chance On-Hit to cause a bolt of lightning that deals 1 to 20 points of electrical damage per minimum level of the upgraded weapon to all nearby enemies.
 * Ruby Eye of Righteousness: 2% Chance On-Hit to cause a blast of holy energy that deals 4 to 16 points of holy damage per minimum level of the upgraded weapon to all nearby enemies.
 * Ruby Eye of Force: 2% Chance On-Hit to cause a burst of magical force that deals 4 to 16 points of force damage per minimum level of the upgraded weapon to all nearby enemies.

These augments can be found in the 40th Anniversary Trading Card event as a possible reward in addition to Haunted Halls of Eveningstar optional end chests, and (infrequently) in the Thunderholme raid chests. Additionally, they are available in the DDO Store to purchase for Turbine Points.[Source]

Named Augments
In addition to the standard augments listed above, there are a limited number of special Named Augments that can be found in certain quests or created through crafting.

Old Epic Augments
The old Epic Augment Crystals will no longer be available after Update 17, and they do not function in the new slots. Existing items won't lose any of their effects, so you aren't forced to update old Epic items. However, if you decide to do any more modification with your current item, you will need to do the following "Cleansing Ritual" to update your item.

To convert an old Epic item to use the new slots, place the item you would like to convert into the Altar of Epic Rituals along with 50 Siberys Dragonshard Fragments. This converts the augment slots on the item to the new system. They retain their colors and can accept the new augments, but can no longer use Epic Augment Crystals from before Update 17. This process will remove all currently slotted Epic Augments in the item, and may also remove other modifications, such as Stone of Change recipes. Players get no refund over this.

Also, as you can see, some of the above change creates "pre-patch legacy items" such as GFL slotted Yellow Slot items and Toughness slotted Blue Slot items. These kind of items will never be available again, much like old version Ascension Chamber loot, ML8 Green Steel items, Epic Seal of the Earth with Acid lore, Epic Brawn's Spirits with enhancement intimidate +5 and so on.

Old Guild Augments
Existing guild augment slots and the guild augment vendors will remain, but new items won’t have guild augment slots after Update 17.
