Each Dungeon provides both a unique challenge and a special reward that can’t be found anywhere else in the game. There are currently 3 dungeons available in the game, with more to come. Dungeons are encountered during the main campaign, and can be used to move to later chapters more quickly. Once several dungeons become available this will represent a significant augment to the overall leveling process.
Dungeons have a total of three floors with the first two floors being randomly generated, offering a different layout to traverse each time while the third floor is where the boss resides. You’ll choose modifiers while exploring the dungeons, increasing the danger and rewards.
Beware, if you die in a dungeon or leave early you will need to use another key to enter.
Lightless Arbor
Deep under the mountains that house the Last Refuge, a massive Titan made of plant and stone has awoken to the encroaching void. Venture into the Lightless Arbor, face The Mountain Beneath, and discover a vault lost to history. The Lightless Arbor can be accessed through the Shrouded Ridge of the Ruined Era, provided you’ve found a Lightless Arbor Key. Conquering Lightless Arbor will grant you access to The Vaults of Uncertain Fate.
Soulfire Bastion
The Soulfire Bastion is an abandoned Osprix battleground turned imperial facility. Within, Fire Lich Cremorus works on his research of the powerful, and highly valued Soul Embers. The Soulfire Bastion can be accessed through the Felled Wood of the Imperial Era, provided you’ve found a Soulfire Bastion Key. Conquering Soulfire Bastion will grant you access to the stores of the Soul Gambler.
Temporal Sanctum
The Temporal Sanctum is a place of study now corrupted by obsession. At its heart lies Chronomancer Julra, a researcher desperate to unlock the power of time and the secrets of the Eternity Cache. The Temporal Sanctum can be accessed from the Ruined Coast of the Ruined Era, provided you’ve found a Temporal Sanctum Key. Conquering the Temporal Sanctum allows you to harness the power of the Eternity Cache, which lets you create a Legendary item.
8.2 Dungeon Ability
Each dungeon has a special ability which allows you to overcome the challenges presented within. These dungeon abilities are specific to their dungeon, and cannot be used outside of it.
Lightless Arbor
Inside The Lightless Arbor you will be granted access to the Pyre Amber. This Amber will follow you around the dungeon providing light and weakening enemies. Taking damage will cause the Pyre Amber to lose light radius. Killing Amber Elemental enemies throughout the dungeon will restore the Pyre Amber’s light radius.
Inside Soulfire Bastion you will be granted access to the Soulfire Shield ability, which can be alternated between Fire and Necrotic to provide immunity from that damage type. Changing the attunement of the Soulfire Shield costs 1 Soul Ember. Soul Embers are gained by killing enemies.
Inside the Temporal Sanctum the boundaries of time are weak, allowing you to use the Temporal Shift ability, which shifts you between Eras at will using the Epoch.
The Temporal Shift ability allows you to very quickly switch between the Divine and Ruined eras without moving. Use this ability to reach the deepest depths of the dungeon as well as to overcome challenging enemies.
8.3 Dungeon Keys
Each dungeon requires a specific key to access it. Dungeon keys have a chance to drop from Rare enemies, Timeline bosses in the Monolith of Fate, and Arena Champions in the Arena. Arena Champions can also drop them as a guaranteed reward upon defeat, provided a dungeon key was selected as a modifier reward during the run. Right-clicking a dungeon key will open the map at the location of that dungeon, for quick traversal.
Lightless Arbor
Lightless Arbor Keys begin dropping from Rare enemies in level 25+ zones.
Each dungeon has four difficulty tiers. Higher tiers increase area level, increase the power and number of modifiers, and allow you to unlock more powerful versions of the dungeon’s reward system. The rewards and enemy modifiers presented at the entrance to the dungeon change once per day and are the same for all players during that time period.
Higher difficulty tiers of the Lightless Arbor allow you to unlock more powerful versions of The Vaults of Uncertain Fate. The higher tier you complete, the higher your reward modifier limit will be.
Higher difficulty tiers of the Temporal Sanctum allow you to unlock the full potential of the Eternity Cache.
At tier 1 the Eternity Cache accepts Unique items with a level requirement of 50 and below
At tier 2 the Eternity Cache accepts Unique items with a level requirement of 65 and below
At tier 3 the Eternity Cache accepts Unique items with a level requirement of 75 and below
At tier 4 the Eternity Cache accepts all Unique items
The difficulty tiers only restrict the level of the Unique item that can be used within the Eternity Cache. There is no restriction on the Legendary Potential of the Unique item that can be used.
Each dungeon has three floors to overcome in order to reach their respective reward. The first two floors each have 2 doors hidden within that grant access to the next floor. These doors become visible on the mini-map when either approached or a certain threshold of enemies killed has been reached.
Each door offers its own unique rewards and enemy modifiers that will persist for the entirety of the dungeon run, but only one door can be selected when proceeding to the next floor. The rewards and enemy modifiers of these doors are random for each run of the dungeon.
Modifiers selected while traversing the dungeons will increase both the difficulty and rewards. Additionally, some modifiers offered within the Soulfire Bastion will alter the results of the Soul Gambler’s items.
8.6 Rewards
All dungeons have a special reward system unique to only that dungeon. Also, each floor of a dungeon has increased rewards based on the difficulty tier and doors selected while traversing to the end boss.
The dungeon bosses can drop one of four Unique items specific to them. Each dungeon tier introduces a new Unique to the pool of Unique items that the boss can drop. However, these Unique item drops are not guaranteed, even at the highest difficulty tier.
Lightless Arbor
Interacting with the door to The Vaults of Uncertain Fate will present you with a sequence of options for modifying the vault contents. Each selected option will modify the vault contents in exchange for gold. Each subsequent modifier will be more expensive than the last based on previous options selected. Declining options will increase the cost, but at a much lower rate.
The higher difficulty tier you complete, the higher your reward modifier limit will be.
• At tier 1 you are limited to 8 mods
• At tier 2 you are limited to 9 mods
• At tier 3 you are limited to 10 mods
• At tier 4 you are limited to 11 mods
Upon finalizing your options and choosing to enter the vault, the door will open to reveal a number of chests modified by the selected options which can then be opened for your reward.
The boss, The Mountain Beneath, can drop one of these four items upon defeat, dependent on the difficulty tier selected.
Soulfire Bastion
Conquering Soulfire Bastion will grant you access to the stores of the Soul Gambler. Soul Embers gathered from killing enemies within Soulfire Bastion can be spent at the Soul Gambler in trade for hidden items. Any remaining Soul Embers are lost upon leaving Soulfire Bastion. Modifiers selected while traversing Soulfire Bastion will modify the results of the Soul Gambler’s items.
The Soul Gambler sells specific item types, such as “helmet”, or “shield” with the possibility of it being any global drop which can be rare, exalted, unique, or set items. The soul ember cost of these item types are randomized for each run to encourage the purchase of different item types. The Soul Gambler also sells 3 Unique items that are exclusive to it, as listed here.
The boss, Cremorus, can drop one of these four items upon defeat, dependent on the difficulty tier selected.
Temporal Sanctum
The boss, Chronomancer Julra, can drop one of these four items upon defeat, dependent on the difficulty tier selected. Unlike the other dungeons, this dungeon boss will always drop a Unique item. There are also some additional conditions for the Unique item that drops:
The Unique item is always accompanied by an Exalted item with four affixes that matches the base type of the Unique item.
For slots with class specific items, the matching Exalted item is always compatible with your class.
Only one Legendary item can be created per successful run of the dungeon using the Eternity Cache that’s accessible after defeating Chronomancer Julra. Please see the Eternity Cache section of this guide for further information on this mechanic.
8.7 Campaign Skips
Dungeons can be used as campaign skips to help modify an alternate characters leveling process so that one doesn’t have to play the campaign the same way each time. These skips do not provide the passive point or idol slot rewards that are available within the areas of the campaign that were skipped. However, there are more passive/idol rewards in the campaign than one can actually obtain, so you’ll be able to pick and choose which quests you do and which dungeons you use to skip campaign sections.
The Lightless Arbor is located off the path from The Surface teleporter, of the Ruined Era. This entrance is found near the beginning of Chapter 3 and exits within The Corrupted Lake, also of the Ruined Era. This zone has a time rift within it that will teleport you to The Risen Lake, of the Imperial Era, which is about half way into Chapter 4.
Soulfire Bastion
The Soulfire Bastion is located off the path from The Risen Lake and then The Felled Wood teleporters, of the Imperial Era. This entrance is found about half way into Chapter 4 and exits near the Kolheim Pass teleporter, of the Divine Era, which is about half way into Chapter 7.
Temporal Sanctum
The Temporal Sanctum is located off the path from the Ruined Coast teleporter, of the Ruined Era, which is accessed via a rift near The Shining Cove, of the Imperial Era. This rift is only accessible after accepting The Sapphire Tablet side quest found within The Oracle’s Abode zone, of the Imperial Era. This entrance is about half way into Chapter 5 and exits near the Radiant Dunes teleporter, of the Divine Era, which is near the start of Chapter 9.
The Eternity Cache is used to forge the most powerful gear in Eterra across all timelines by sealing specific items inside to merge them into something even greater – Legendary items. Centuries of time are needed for creation, and bypassed only by a Traveler using the power of the Epoch.
The Eternity Cache is located within the Temporal Sanctum dungeon and only accessible after defeating Chronomancer Julra. The cache requires a Unique item with Legendary Potential and an Exalted item of the same type with 4 unsealed affixes in order to create a Legendary item.
Both items are placed within the cache and left to merge over centuries of time by using the Temporal Shift dungeon ability to traverse between two eras. This process will transfer a number of random affixes from the Exalted item to the Unique item equal to its Legendary Potential, which will then create a Legendary item.
9.2 Legendary Potential
Unique items have a chance to drop with Legendary Potential. This stat ranges from 0 to 4 and determines the Unique item’s ability to be transformed into a Legendary item within the Eternity Cache.
The quantity of Legendary Potential that a Unique item drops with is only influenced by the level of the zone in which it drops. Corruption, increased item rarity, character level, or any other modifiers have no effect.
The amount of Legendary Potential that a Unique item will generally drop with is relative to the item’s base power. High powered or very well scaling Unique items will on average drop with less Legendary Potential than low power or leveling Uniques. This is done so that most Unique items will have a more similar overall power potential.
To create a Legendary item, you need a Unique item with Legendary Potential and an Exalted item of the same type with 4 unsealed affixes. The Eternity Cache will ignore any sealed affix on the Exalted item so it must always have exactly 4 unsealed affixes in order to work.
For example, any Exalted, 4 affix Shield can be used to create a Legendary Bastion of Honour.
Both the Unique and Exalted items are placed into the cache in the past (the Divine Era) and the Temporal Shift dungeon ability is used to traverse into the future (the Ruined Era) where a Legendary item will now take their place. The Legendary item is the same as the Unique item but with affixes added to it from the Exalted item.
Legendary Potential determines how many affixes will be extracted and transferred from the Exalted item into the Unique item to make it a Legendary item. The affixes are selected at random and cannot be influenced in any way.
A Unique with 1 Legendary Potential will transfer 1 random unsealed affix from the Exalted item.
A Unique with 2 Legendary Potential will transfer 2 random unsealed affixes from the Exalted item.
A Unique with 3 Legendary Potential will transfer 3 random unsealed affixes from the Exalted item.
A Unique with 4 Legendary Potential will transfer all unsealed affixes from the Exalted item.
Only one Legendary item can be created per successful run of the Temporal Sanctum dungeon. Each difficulty tier of the dungeon allows for higher level Uniques to be used in the creation of Legendary items.
Tier 1 allows the Eternity Cache to accept Unique items with a level requirement of 50 and below.
Tier 2 allows the Eternity Cache to accept Unique items with a level requirement of 65 and below.
Tier 3 allows the Eternity Cache to accept Unique items with a level requirement of 75 and below.
Tier 4 allows the Eternity Cache to accept Unique items of any level.
