What's a good element to pair with the element of darkness for my magic system?
Edit: I've been told my question is a little too opinion based. I'll edit/clarify the question to the best of my limited intelligence and capability, but if its still too opinion based I won't fight it being closed. Thank you to everyone who contributed/may contribute and I apologize for the inconvenience.
My magic system involves groupings of elements called domains which have a unique property not specific to either element in said domain. A user of a domain can not only manipulate their elemental affinities but conjure said element as well. This is done using the base magical energy in my system called "Phantasia".
As the title implies I'm looking for a element to be paired with darkness. So far I've been using "void" as the element paired with it. It being negation of other elements or properties. But I've started to dislike it due to the negation aspect encroaching on the unique property of the domain, that being restriction. The restriction property allows someone to limit themselves by imposing restrictive rules on their abilities. While doing so will hamper them in some way, the greater the restriction the greater the power is gained in return. They can also restrict the abilities of others. I felt the negation aspect of the void element was too similar to the unique property not meant to be specific to either element, in this case restriction.
With this in mind what's a good element to pair with darkness that fits the unique property I've established?
Also just so people don't suggest elements or powers I've already put in other domains, the elements I already have and their unique properties are:
Fire and poison. Unique property: Infliction. The ability to inflict lasting damage by chipping away and disintegrating something/someone or status effects often in the form of poisons or burns.
Fauna and flora. Unique property: Absorption. The ability of a person to absorb enemy Phantasia powers and constructs into their own Phantasia.
Earth and metal. Unique property: Creation. 183
The ability to create items that can only be stable if shared.
Water and ice. Unique property: Enervation. The ability to slow and weaken the bonds of Phantasia from their enemies, halting their functions.
Light and sound. Unique property: Specialization. The ability to share Phantasia with others to "specialize" in certain benefits. Often in the form of support skills or healing. Think buffing stats in a video game.
Wind and electricity. Unique property: Channeling. The ability to channel incredible amounts or hostile forces of Phantasia with little to no harm. Often used in the form of counter attacks.
Space and time. Unique property: Distortion. The ability to create distortions in the Phantasia from their enemies or around them and then manipulate said distorted Phantasia to their whim. Usually in the form of creating unique rules or properties to the Phantasia they distort.
The abilities involving mind reading, mind manipulation, dream manipulation, and illusions are base powers in the magic system not specific to any domain.
As can be seen with the grouping of fire and poison together, I'm don't need the element suggestions to match perfectly in substance with darkness. Just the overall theme of the domain it's in and it's unique property. In the case of fire and poison it's the ability to inflict lasting damage or status effects. While the domain darkness is in is a more rogue like one. Whose roles are primarily stealth via restricting/limiting their own presence as well as trapping/capture by restricting the powers of others.
I also don't really need the element to counter or be opposite to the domain of light and sound. Since I have it set up that any element can be sufficient against any other in a battle provided the willpower and other factors.
A best answer should include an element type power not expressed in the above list of elements already present in the system or in their unique properties. 227
