Should there be a limit to getting out of trouble with extraordinary power?

[Ground Cinnamon]

Just a personal opinion, but I find it really annoying when it is hinted that a character has some power, maybe even use it, but then can't seem to use it again for page after page. That is fine for 50-100 pages after the power is revealed, but when it is the whole book, or worse a whole series of books, it just becomes a painful waiting for the reader. To much cliff hanging makes a platou.

I'm all for characters doing things beyond their limits but it can never be a predictable effect each time - the result has to be completely surprising.

Later on they can perfect their techniques and figure out how they did it that first time.

In the mean time perhaps consider that the desired out come is achieved,but it also creates an unintended effect (for instance the fire blast could be so bright that it severely effects his eye sight for a while... that'll teach him!)
