Vessels act as a player's main resource to cast invocations and skills. Each element is represented with a base vessel, along with hybrid vessels, which can be used for more than one element. Some vessels even have special abilities.
- Players must have 20 vessels for a standard deck.
- Vessels are kept separately from the main deck and form a side deck of their own.
- There is no limit to the number of hybrid vessels a player may have in their vessel archive.
The repository acts as an invisible storage for essence. Whenever a player discharges a vessel, essence is generated and put into their repository for use that turn. For example, if Player A discharges a Light vessel, one Light essence will be added to their repository. Please note, however, that repositories, by default, empty at the end of their player's turn.
