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. (Epic Augments can still be found on some legacy items, but these have become very rare. Guild Augments are now completely obsolete.)

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

Augments tend to be named as follows:
 * Colorless Augments are known as Diamonds.
 * Red, Yellow and Blue Augments are Rubies, Topazes and Sapphires respectively.
 * Green Augments are Emeralds, and Orange Augments are Citrenes.
 * The exact name of Purple Augments is unknown as currently all three existing ones have special names; however, the set description for the indicates they are likely known as Amethysts.
 * Note that these augments are not to be confused with Gems.

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."

Items with augment slots

 * Named items
 * Most newer named items have at least one augment slot. Raid items and higher-level items usually have two. Minor artifacts have 3.

5% of generated items have an augment slot. All types of augment slots can appear on random loot. Items with 2 slots are very rare but possible. On random items, augment slots are a bonus feature in addition to other effects, such as Enhancement Bonus, prefix, or suffix.
 * Random loot

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

Note: When you prepare a blank item for Cannith Crafting (disjunction), blanks with augment slots have a minimum level higher than one (up to 9 for dual-slotted blue+green blank). However, when you apply a minimum level shard, it can reduce the ML of the blank.

Augments
Augments are a kind of miscellaneous item, they do what Augment Crystals used to do before and more. Augments can be stored in an Augment Bag (available only from the DDO Store) or in the Crafting Storage of the Shared Bank.


 * Common augments
 * 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.
 * Various vendors in DDO sell augments; see Purchasable augments
 * Some augments are also sold in the DDO Store (bound to account).


 * Uncommon and named augments
 * These drop in specific chests of specific quests and often have unique effects.


 * Crafted augments
 * You have to prepare these in crafting devices for various ingredients.


 * Dino augments
 * The Isle of Dread has a crafting system that uses augment slot mechanics. Dinosaur Bone crafting has its own craftable dino augments and items from that pack can include distinct dino augment slots.

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 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. 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.
 * 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.

Standard augments
This table lists the common augments available in DDO. They are available at minimum levels 1, 4, 8, 12, 16, 20, 24, 28, and 32. The effect matches Cannith Crafting in power level (This is not true for damage augments.For example lv 28 augment gives +8d6 while lv 28 CC only gives 6d6, lv 24 is 7d6 vs 5d6, lv 20 is 6d6 vs 4d6, lv 16 is 5d6 vs 4d6, lv 12 is 4d6 vs 3d6, lv 8 is 3d6 vs 2d6)). For example, an ML8 Strength augment grants +5 Strength, just like an ML8 cannith-crafted strength item would.

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

Purchasable augments
Some augments can be purchased from vendors and collectors in Stormreach and beyond. Some notable vendors are listed below. For a full list, see the Purchasable Augments page.


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

Named, uncommon, and 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 chest loot.

Essence augments
Transform a Raid Item into a level 30 Augment bearing an enchantment specific, and typically unique, to that item. These Essence augments can be crafted in the Soulforge altar in the Hall of Heroes (lower level, first room, SW corner).

Set augments
These level 30 Set 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. Be aware that slotting a Set Augment into an item with any existing sets will suppress those sets while the Set Augment is slotted, so you should avoid slotting set augments into items that are part of sets you intend to complete.
