Self powered scrolls

[hcobb]

In this variant the writer determines before starting writing how many points of fatigue the scroll will provide towards the casting of the spell on the scroll. (Usually just the initial casting cost, but can include multiple turns of maint if desired.) The time to write the self-powered scroll is extended by one day (requiring another DX roll or the entire scroll is lost) for each point of fatigue it will provide towards the spell.
