Also, one other thought... I recall when looking at the effects from G&K, the Great Prophet has a pair of effects associated with the founding of a religion (a burst of light and something else). While the number of attack spells that don't actually fire projectiles is probably rather slim, I do wonder if it's another possible effect to tie to a spellcasting -- perhaps for some kind of Charm or Death spell or whatnot, that could hurt an enemy without actually firing something at them...
You could do a "Dagger Storm" by using the Trireme's attack effects...and the effects from a rifle flash might look good as well.
I would love to see what everyone can come up with, I am sure there are a lot of effects to explore.
So, it sounds like a tutorial is in order. I will throw something together to get the basics down so that we can see what everyone's imagination can unleash!
