And finally, in my experience... you will have to "beat the dragon" even when you pay in gems the last piece unless it will be the 3rd and last dragon to get... then, if you paid the last piece with gems have no need to battle him BUT if no-gems used... you'will have to.

Buying with gems all... the whole quest's partes together at once... or if there are at least 2 parts to-do of the you decided to pay for it,  are the only way to skip/avoid "beat the dragon" I've know for sure.
