There was behind the scenes complciations with settling on visuals, what I actually want to establish about this spell, and how I'm going to finish off the rest of Ellen Demo (which I want to conclude this week).
This is what I finally settled on, though I'll elaborate a bit more on the spell in the next comic, too. I wanted to establish that the effect wouldn't go on indefinitely, fueled by ambient magic energy, but I don't want to get too specific on its exact limitations, either. I'm going for "vague idea of its precise capabilities" over here.
(Accusations that I'm doing that so I won't have to worry about contradicting anything in future stories with it are on the ball)
