My group just started playing the Call of Cthulhu LCG, and after a few games under our belts, I have a quick question about disrupts. Specifically, when can a disrupt be played or activated? Is it only after a "triggered effect", and are those effects limited to Action, Response, Forced Response, or another Disrupt? Or can a disrupt be played without a triggered effect? Or does resolving a struggle count as a triggered effect?
For an example, I'll use the card Rites of Luveh-Keraph (an attachment):
Disrupt: before a triggered effect resolves, pay 1 to give attached character +2 skill or 4 arcane until the end of the phase.
In this case, you can't simply pay 1 to activate the attachment during the white box Action sequence of a story phase unless something triggers it, correct? And if something does trigger this card, it can be played at any time during the story phase, right?
Thanks for your help!
