I think you can only use that once a day, though. And doing it repeatedly would likely make us pass out.
I thought there was a penalty when any sequence used fast after each other.
So for example using Destruction once. Then casting it instantly again. And again. and so on would be very risky, since each time the chance of something horrible happening would increase rapidly.
This would make it dangerous to try to get past the shardplate by quickly spamming btw. I believe the rate at which the danger increased was somewhere in the previous thread.
But say waiting 1 hour between castings would be safe.
@Mazrick, can you confirm? Or is there something special about Regeneration that makes it 1/day?
Also, could you tell us the risk of repeated fast castings of a sequence, and would it be smaller (or higher) if we used higher destruction skill? Lets say we buy Destruction 7, and bombard Drogo with it 5 times. What would happen?
Maxing out fire would probably provide us with complete control over fire in it's natural form. So probably something that would let us do massive damage to and possibly rout armies with enough effort and some really good rolls. Of course, the trouble is getting to Naming 10 for anything.
The trouble is that it would be nice to get something that would help us NOW. IF we get out of this mess, we will hopefully have many months to train Naming in Winterfell before OP returns and things go to hell. Fire 4 does not really help all that much in the immediate future.
