I would like to take a moment and express my admiration and appreciation for Ray. He is obviously facing challenges, but he makes up for his deficiencies with enthusiasm. He is having fun, and I am proud to be his friend.
Post on Abe. Post and have fun.
If you're using Aquam to (for explosions under water), you don't need Igenm - and explosion is just a sudden (usually violent) expansion, the fire's just a side effect of how to most easily cause such an expansion.
But using Aquam, you could create a sort of 3D Wave effect that pushes water to whereever you want it, and with enough levels, that could certainly be a destructive effect.
There's a ReAq 3 guideline that allows you to change water to steam. Could that be used underwater to create some sort of "explosion"? Or would just the Base 10 control in an extremely violent way be the way to go?
That's actually a pretty neat concept, but -10 is way too intense, probably even for a Major flaw. I'd go the route that half-demon children go, where, and somebody correct me if I'm wrong here since I'm AFB, they are treated as twice their age and roll two Aging rolls per year instead of one. It's a balancing factor for the Virtue in the half-demons' case, but makes a legitimate Flaw on its own.
