Game Mechanics - Mastery
Masteries are special non-object player functions and are typically granted by various effects. Players can only have one mastery at a time.
General Rules
If you get another mastery, it replaces your current mastery.
Cards interacting with certain masteries may have symbols and icons related to that mastery on the card.
Cards that track and represent masteries cannot be placed or used in any decks (Main, Material, Sideboard) and only serve to visually reflect the active Mastery.
Table of Masteries:
Servile Possessions

Servile Possessions designates cards in the banishment with Omen counters on them as Omens. The mastery and any cards that refer to the number of Omens or characteristics among Omens will refer to those cards in banishment.
Servile Possessions has a modal trigger whenever your champion attacks depending on the number of Omens in banishment, listed below.
These modes are mutually exclusive and not additive.
The modes are statically applied to attacks; they are not added to an attack via any trigger or triggered ability.
1 or 2 Omens — That attack gets +1 power.
3 or 4 Omens — That attack gets +2 power.
5 or more Omens — That attack gets +3 power. Draw a card into your memory.
Shifting Currents


Shifting Currents has four modes. Each mode is represented as a "direction" of either North, South, East, or West. Shifting Currents can only be set to one mode at a time and changing the mode will remove whatever mode it was previously set to.
The starting mode is in the North direction.
If a card's rules text references any of Shifting Currents' modes, it will be reflected as direction icons on the bottom left of the card.
An adjacent direction for shifting currents is defined as the following: North and South are each adjacent to both West and East; West and East are each adjacent to both North and South.
