Live PATCH 5-20-14 Note: "Updated all spells which
use Remove Detrimental and Cancel Beneficial spell
effects to use a new method. The chances for those
spells to affect their targets have not changed unless
otherwise noted"

Support added for new base values to give
a nearly equivelent result.
(Ie. Will work for values pre and post change)
