At the beginning of each players upkeep put a
charge counter on this emblem. Then, if there are
X or more counters on this emblem (X = number of
players alive), remove them and put two descent
counters on this emblem.

At the beginning of each players upkeep each player
creates Y treasure tokens and this emblem deals Y
damage to each player, where Y is the amount of
descent counters on this emblem.
