==== Taint and Channelers ====
Taint poses an especially insidious hazard for channelers, who gain a 'taint pool' whenever they gain taint. This pool can be used to cast spells, spending taint points in lieu of spell energy. All channelers who have a taint pool are considered 'Tainted Channelers', and face corruption, as described below. 

Taint is spent on a 1-1 basis in tainted areas, and a 2-1 basis in non tainted areas. Taint is refreshed at a rate of 1 point per hour and fully upon rest while in tainted areas. In non tainted areas, taint does not recover at all, and is lost at a rate of 1 point per day. For purposes of taint cost, taint recovery and taint loss, any area under the influence of a Black Mirror counts as tainted, even if the location itself does not cause taint.
