Clerics of Takhisis are granted a rare and terrible boon: by her leave, they
may call upon a single aspect of another dark deity. This channeling does not
make them priests of that god, but it allows one chosen reflection of their
power to manifest through the Queen of Darkness.
When a cleric casts Aspect of Evil, they must choose exactly one available
power of another dark god. This choice remains until the cleric meets death,
at which point the aspect fades and must be chosen anew if the cleric wishes
to wield it again.
Example:
cast 'aspect of evil' 'fatigue'
There is one exception to this: Morgion refuses to grant the power of Rot to
anyone but his own true servants.
