Hidden Skill

This skill represents the infusion of qlippotic power, the energy associated with dark gods, into your essence.  As the degree of
this infusion grows, the trauma of exposure to such energies becomes less and less, even to the point where one can take these
energies into oneself and be restored by them.  However, the greater the degree to which one is infused with the power of the
qlippot, the more vulnerable one becomes to the energies of the sephirot.

Qlippotic affinity can be increased by exposure to qlippotic power, as well as degraded by exposure to sephirotic power, changing
more quickly according to one's astral perception.  If one also has sephirotic affinity, these capabilities will slowly degrade
each other over time.
