Not sure if this belongs here or in a different section, but…
What are your takes on the Whisper’s Summon special ability? What do you consider to be a supernatural being (would another Whisper count)? What does this “magnitude” business mean to you?
My suggestion:
When you summon an entity you decide a set of actions that you want them to be good at. The entity gets a number of preferred actions equal to the amount of stress you take, and has a dice pool equal to 1 less than this. The entity takes -1d if it does not take a devil’s bargain when preforming actions (but does not gain +1d for taking the devil’s bargain) and will not gain the benefits of assists or background (as the entity will refuse assistance or physically is unable to be aided by it, and are already assumed to be adding their background to their set of actions).
The type of beings that you can summon include everything that is listed on page 41, as well as demons and any other whisper, or character that has any whisper powers. Summoning whispers takes 1 additional stress, and summoning someone that has whisper powers takes 2 stress if they have 2 whisper abilities, and 3 stress if they have 1.
What are your suggestions and ideas?
I’ll have guidelines for this in the full book. Summoning another Whisper is an interesting idea.
