Augment Slot

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:

NOTE: The on-screen description of Augment slots neglect to mention that Colorless augments can be used anywhere. It's good to mentally add the words "...and Colorless" to the description. For instance, "This item has a Purple Augment Slot. It can be combined with a Blue, Red, or Colorless Augment."

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 can be found on random treasure since Update 46.

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

Prior to Update 32 sockets on on a Craftable item added to the item's minimum level. However now colorless and colored augment slots on an item do not increase an items total enhancement value.

Augments
Augments are a kind of miscellaneous item, they do what Augment Crystals used to do before and more. Prior to Update 48, the benefit bestowed by an augment was typically lower than the normal item enchantment of the same minimum level.


 * 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 Tokens and Greater Tokens of the Twelve are lower than their previous costs.
 * Select level 12, 16, 20, and 24 Augments can be found in Gianthold in exchange for Ancient Elven, Giant, and Dragon relics (levels 12 & 16), or the restored versions thereof (levels 20 & 24). Level 24 augments additionally cost 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 changed Collectable turn-ins to provide select 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.
 * Update 28 added select augments from 1-20 to the Mysterious Remnant vendor.
 * Update 48 upgraded existing scaleable augments, changed the augment display and changed the augmentation method.

Augments can be stored in an Augment Bag (available only from the DDO Store) or in the Crafting Storage of the Shared Bank.

Usage
From the inventory screen, click the 'Augment Item' button at the lower right of the window, this will display a popup-window of the same name. Drag the unlocked item to be augmented to the empty position on the popup-window, this will display filled and empty augment slots on the item. Drag an appropriate augment onto an empty slot of an appropriate color and it will lock into place, applying the effect of that augment to the item. Close the popup-window when you have finished augmenting the item.

At any point, you can replace the augment you have slotted by placing a new one in the same slot. 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 the old augment back. It is also possible to take an augment off from pre-slotted named items using it. 

Every augment has an associated minimum level requirement to use it. The common (non-named) augments move up in increments of 4 levels at a time: 1 (technically 0), 4, 8, 12, 16, 20, 24 & 28. 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.

Update 48
Update 48 introduced a revamp of the augmentation system, as a result of this augment slots and augment-gems have been upgraded: NOTE: No items or augments currently held in a bank will be upgraded, they must be moved to your inventory and a logout/login cycle completed to cause the upgrade process to trigger.
 * Any augment-gem that is not slotted into an item when you log in will be upgraded upon login.
 * Any item which has all augment slots empty, will be upgraded upon login.
 * To remove old-style augments from items, a  can be purchased from cannith crafting vendors for a nominal cost. (2 copper)
 * Simply double click the  to open a window, then drag and drop an unlocked augmented-item to the window, augments will be displayed and can be removed.

Available Standard Augments
The below listed Augments are implemented with the introduction of the Augment system, as well as the new augments added in Update 48.

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.
 * This page shows this information in a different arrangement. Augments by Level

New Augments will continue to be added in future updates. 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.

(The values in this table have been updated to U48. New sapphires of Dodge, Stunning, Shatter, Vertigo, and Accuracy, and topazes of Spell Penetration and Damage have been added.)

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


 * Lahar in The Twelve sells augments for.
 * Collectors throughout Stormreach will give you a semi-random augment if you turn over enough of the right collectables, or you can choose a specific augment if you pay with Astral Shards.
 * Vendors in Gianthold will trade you augments for your Relics (and/or Commendations of Heroism). These augment vendors are in a group in the far western Gianthold, just south of the large bonfire.
 * They are...
 * Ruskin Blackboot, Lvl 12 augments
 * Meliager Ei'n, Lvl 16 augments
 * Broag Umber, Lvl 20 augments
 * Agate Twistiron, Lvl 24 augments
 * (and see also Orzabal Stonesmasher, to exchange relics of one type for another)


 * Monster Hunter in the Hall of Heroes will trade augments for Mysterious Remnants.

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

Additionally, several named items come pre-slotted with an augment. Some are listed.

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

Named and Uncommon Augments
The normal Named augments and Uncommon augments can be acquired as normal chest loot.

Essence Augments
Transform a Raid Item into a level 30 Augment that embodies it. These Augments can be crafted in the Soulforge altar in the Hall of Heroes.

Set Augments
These level 30 augments can be slotted in any augment color slot. They can be crafted in the Hut from Beyond (lower north harbor) in the Cauldron of Cadence. The Augment Set bonus takes priority over Item Item Set bonus, when slotted into a Set Item. In other words: "Slotting a Set Augment in any Augment Slot of a Set Item will override its existing Set Bonus to Augment Set Bonus."
