Buttress Charm
E/F/M:
This Charm is meant to reinforce a Casting, previously activated by the caster, which is still in force.
In addition to the base cost for a Grade II Casting (35 Heka points), the persona employing the Buttress Charm must expend an amount of Heka equal to the base cost of the Casting in force which will receive the benefit of reinforcement.
Ten percent of the total Heka expended will then be added to the cost of any other caster's attempt to dispel the subject Casting, and such attempts will also be one Difficulty Rating harder to make.
A Special Success will add 50% of the total Heka expended to cast this Charm as a reinforcement (in addition to the cost of dispelling the subject Casting). A Special Failure will act as a Disjunction, automatically dispelling the subject Casting.
