I recently got my hands on the Legend System, and I'm trying to digest its inner workings to conduct a game of it.
I'm having trouble understanding how the ability Giants in Iron, from the Mechanist Savant Track, works:
Giants in Iron
As an immediate action, any ally within your Assemblage can choose an active Generator or Hunger spread you created. If that ally does, that ally may create a 45 ft radius Decimation spread originating from target square of that ally’s choice within your [Medium] range of the square from which the chosen spread originates, then you end the chosen spread and gain one automaton.
Whenever an ally creates a Decimation spread, if that spread did not end, that spread deals damage to each opponent within its area equal to your character level. For each opponent in that spread, as a [Dispelling] effect, the ally that created it ends up to one effect of that its choice created by a spell or spell-like ability that has a duration and that originates from that opponent or targeted that opponent. End that spread. (You are your own ally.)
Up to now, the system seemed rather easy to understand, but this ability blew my mind. How is this supposed to work? I can't make heads nor tails of it!
