Re: Episode 2-7
Two hours later:
Aaron finds the spell. It's a powerful spell (power level 9 in game terms)so it surely wasn't cast by a rank amateur. The spell is cast by drawing the appropriate mystic symbols pictured, placing a map of the area you want to affect over the symbols, and do an hour long ritual with chanting, candles, etc.
Negating the spell is easy. To keep it in effect, the map must remain on the mystic symbols. Remove the map from the symbol area and tear it up, field drops.
OCC: Decided to give you guys a break on the spell research time, if we'd stuck to the research time rules, it would have taken until sunrise or close to it.
