Oblation is the act of meditation at a Hallow for the purposes of regaining Mana.
Oblation is the most common form of Gaining Mana, where the mage restores their Mana via an hour of meditation at a Hallow.
This is a very efficient process, but it is a common frustration for some mages, as access to a Hallow isn’t always easy to come by.
A mage can perform Oblation without a Hallow if they have a Legacy. It is a massive advantage and often a much-desired benefit for mages without Legacies.
