Ligomancy

Ligomancy, also known as binding magic, was a discipline of magic that focused on the links between objects, souls and auras to strengthen and reinforce. Imagine ligomancers as puppeteers or guitarists; using invisible strings to tug on magic. Examples of ligomantic practices included, but were not limited to the following;
* Using voodoo dolls to cause effects on the people they depicted
* Using tokens such as gems, stones, coins, or idols to store magic, or casting spells through them
* Placing tokens on people to affect them with enchantments
* Binding spells to locations, drawing down local energy (such as binding all nearby static to one point to cause a lightning strike)
* Using circles, drawn sigils, and glyphs to trap and store energy and spells
* Casting miniature spells on object and amplifying them
Ligomancy was a common practice for some paladins. It allowed them to bind cleansing energy to physical places, or to unbind evil energy. It was a lesser-used discipline of magic, and neither inherently good nor evil. 
As a ligomancer, you gained the following cantriplike ability. It effectively is a free Prestidigitation/Thaumaturgy/Druidcraft cantrip, which is harmless, you can cast at will, as an action, and lasting up to a minute, but with a much more thematically focused effect. It only had a somatic component, which was usually a small but meaningful hand symbol of your choice.
*Matterbind. Whilst holding a small object, you can act on a large object that shares properties (shape, material) with it within 10ft. Alternatively, you can act on the held object in a manner that you wish to affect the target. For example, you could light a twig in your hand, and a large lantern nearby could light. You could pour water on a piece of scrap wood, and a nearby table would become suddenly soaking wet. You could stab a needle into some fabric and point at a nearby tent, and it would be ripped wide open.
== At Higher Levels ==
When you gain the ability to cast spells of 3rd level, you also gain an additional trait from your chosen domain of cruormancy.
* Tokenbind. You can spend time over the course of a long rest marking a nonmagical object as a token. This could include inscribing symbols on a throwing knife, enchanting a small stone to give to a friend, a lucky playing card, or something similar. When you cast a spell with a range of touch, make a melee spell attack, or make a melee weapon attack, you can do so through the space containing the token. Doing so consumes the token. You can only have one token at a time.
