When a Demon is left side up (unbound), then it deals damage to the Witch owning it.
Deals black cubes equal to the cube value on the Demon, and hits the Coven, by discarding cards from the Locus.
I would like to ask, which cards are discarded?
Is it the player's choice, taking card not to deplete all Spells from one slot of the Pentagram?
Which deck takes those hits?
It takes from the lowest locus first when it is empty it moves to 2 then 3, etc.
