cumulative summon?

[megaplayboy]

Is it possible to use the cumulative advantage with summon?
e.g., opening a gate for a demonic invasion--x number of demons come through per phase, up to the cumulative limit...

By a strict reading of the rules, no -- Summon doesn't require the application of a total rolled on the dice to a defense, as described for Cumulative. However, if Cumulative can be adapted for Flight in SH, a GM could certainly allow what you describe if he wanted to.
