Hi all,
This is in regards to the rules on prolonging evocations (YS:259). As I understand it you can use the standard action of a turn following the casting of an evocation to 'add more energy' to it and so increase the duration of the effect by casting another spell where each shift of power is equal to another exchange of duration.
I am wondering if it possible to use this mechanic to extend the duration of a rote spell. The reasons for this are that it says "...you don't have to sacrifice the efficacy of the original spell- it keeps the rating of the original roll." and the spell in the example is Harry's shield spell, which I believe is one of his rote spells.
The rules for rote spells say that "Any change in the parameters of the spell disqualifies it from being rote". Since the 'original roll' of the spell is not modified under the rules for prolonging spells that means it wouldn't change the rote spell either right?
