The Perfect setup of your style

The Signets are unique passives granted by equipment. They cannot be learned with skill points.
While equipment provide the usual bonuses in Luna Obscura, some of them may also provide a higher level of a given signet, which is a unique effect you can build-up by stacking multiple effects. Equipping multiple pieces of equipment that grant the same signet will stack their level bonuses, providing increasingly higher effects the more of that effect is stacked.
With a wide array of signets available, each with their own gameplay changing characteristics, Signets are a unique way to change how a character works. With freedom to gather a wide variety of lower level effects or double/triple-down on a few choices, enabling special effects on builds and a unique, completely new playstyle.
By design, signets are easy to understand and use, work automatically and require no micro-management, being all passive effects that automatically work as they are granted.
Finally, some signets are rarer than others, with stronger effects where getting even Lv2 can be a huge game changer.
Note: Signets are similar to "Set Skills" from Monster Hunter games, where you wear multiple pieces with the same traits to level them up.
List of all Signets

There is a total of xx Signets in Luna Obscura, each of them improving a unique part of the gameplay style.
There are 3 key points to keep in mind in regards to signet levels:
- Signets are capped to Lv20.
- Each Level bonuses, granted for each level the player has of a given signet.
- Key Level that grant unique effects and change how a given skill behaves.
They still grant a smaller, constant bonus per level increased. But getting key levels is the most important part of any Signet build.
In-depth details about each can be found ingame.
