Power Stone is a Relic.
How to Get
Beat the relevant mission in The Tale of Horus Traver
Strategy
This is a more reliable way to ramp in Eternal, as relic removal is limited, and units with similar effects, such as Avirax Familiar and Initiate of the Sands are weak to the many forms of unit removal.
A deck that might want to play this is a control style list that has its units die to Harsh Rule style effects. Or a Praxis () list that runs Kindle to ramp into very big threats, very quickly.
