- Ellen tries to zap Not-Tengu
This is another thing I fretted over. I did like the idea of her getting more powerful versions of many of her spells by putting her hands together, and I was carefully considering exactly how it would work with the shrink ray in partiuclar.
Ultimately, however, doubling pretty much anything is a bit too much. Frankly, FV5 can only be doubled because it's something a lot of people have basically asked for in the past, and it's not that big of an issue to have it be a thing even if it won't show up much in canon.
Meanwhile, shrinking, weight, muscle, height... They all get out of hand really quickly if they universal doubling of beam spells is a thing. It's a can of worms best unopened.
Besides, if I want Ellen to ever have a better shrink ray or something, I am writing this, I have that option. I don't need to spill worms everywhere to do it later.
