Oil

Oils are currency items that can drop from Blight encounters. Using them on certain items gives these items an anointment, which can modify them in various ways.

Mechanics

Sister Cassia's Annointing interface used to add the Command of Steel passive skill to an Amulet

Oils can be applied by the player via Cassia, to Blighted maps, rings, amulets or blight unique items in order to add new modifiers or the effect of a passive skill:

Type	Oils	Effect
Blighted map	1x	Increased monster pack size and effect depending on the oil
Rings	2x	Buffs to Towers
Amulets Blight unique items	3x	Allocate a notable passive skill from the passive skill tree without spending a skill point or being connected to the rest of the allocated skill tree.

• Blighted maps can have up to three anointments at a time. Multiple copies of the same oil are additive. Example - 3 clear oils with 10% reduced monster movement speed give a total of 30%.

• Anointments on equipment take up the enchantment slot.

• Allocated passive nodes on the Amulet behave as if the node were taken manually. In other words, socketing a Timeless Jewel and anointing a passive node will grant the new, transformed modifiers. It will not grant the old, original modifiers.

• Vendor - Three vials of oil can be vendored to create one vial of oil of the next tier, much like essences. For example, one will require 3^12=531441 . As such, it should only be used when one has a vast excess of one type of oil or needs a small amount of another type.

• Annointment order - There are 13 oils, combinations allow the use of the same oil more than once, and the order does not matter. Thus, there are 455 possible combinations of both notable passives on the tree and Blight-only notables (non-cluster jewel notables). Some combinations do not yet have an associated notable.

• Tainted Oil - is not used for any anoint combinations, but can be used as a fourth oil to anoint corrupted items.

List of Oils

14 different oils exist in a strict progression system.

List of Blight uniques

These specific uniques can also be anointed. They gain the same passive skills that those oils would apply to an amulet.

Sepia Oil	Towers deal 25% more Damage 6% increased Pack Size
Amber Oil	25% reduced Cost of Building and Upgrading Towers 6% increased Pack Size
Verdant Oil	45% increased Experience gain 6% increased Pack Size
Teal Oil	Blight Monsters spawn 30% faster Encounter Duration is 50 seconds shorter 6% increased Pack Size
Azure Oil	Varieties of Items contained in 5 Blight Chests are Lucky 6% increased Pack Size
Indigo Oil	Blight Encounters contain up to 3 additional Blight Bosses 6% increased Pack Size
Violet Oil	Lanes of Blight Encounters have 25% chance for an additional Reward Chest 6% increased Pack Size
Crimson Oil	Varieties of Items contained in 12 Blight Chests are Lucky 6% increased Pack Size
Black Oil	7% chance for Blight Chests to contain an additional Reward 6% increased Pack Size
Opalescent Oil	Varieties of items contained in 18 Blight Chests are Lucky 6% increased Pack Size
Silver Oil	80% increased Quantity of Items found in this Area 6% increased Pack Size
Golden Oil	30% chance for Blight Chests to contain an additional Reward 6% increased Pack Size

Note: Blighted maps may be anointed up to three times, and Blight-Ravaged maps may be anointed up to nine times, where each anoint's modifiers stack with each other. This is why anointing Blighted maps anointed with three Amber Oils is considered the current easiest method for clearing Blighted maps, as this combination of anointments results in a 75% discount on Tower building costs.

3.13.0	Due to a bug being fixed with the "Blight Chests are Lucky" stat from the Crimson and Teal oil Blighted Map Anoinments that causes the stat to apply to each lane, we've adjusted the values of these Anointments. Teal Oil now grants "5 Blight Chests are Lucky" and Crimson Oil now grants "10 Blight Chests are Lucky". The Blight Ring anointment that causes minions from your Scout Towers to have increased Life now instead causes your Scout Towers to produce an additional minion. Existing items with this anointment are unaffected.
3.11.0	(In Development Manifesto ) We've added a new between the and . This has made more common oils slightly rarer, without making rarer oils even rarer. Some Notables will have updated oil costs as a result of changes to the passive tree. Not every Indigo Oil combination on Amulets will yield a notable yet. There are no new Blighted notable passives and two existing Blight notable passives are now on the passive tree. New Ring and Blighted Map anointments have been added. Added a new type of Oil, Indigo Oil, in the middle of the Oil progression. Added 13 new Ring anointments that utilise the new Indigo Oil. Oil costs for Notable passive skills can now be revealed by holding alt while hovering over the passive.
3.8.0	Introduced to the game.
