Canceling Spells

Canceling Spells is on B237 after Casting Spells. M10 reiterates it.
the Kill Switch perk allows avoiding the FP cost
Cancel Spells in sorcery approaches emulation but due to not using one spell at a time limit like remove Curse allows 1 FP to dispel an unlimited number of spells.
*this appears to imply that you can waive the will roll you would normally get to stop the disruption of your own abilities

No clarification if it might be done as an active defence, like for example if a child is attempting to pick up your Flaming Sword and you want to prevent them from being burned by touching it.
