My experience has been that it takes much closer to 2 hours to master a spell with baseline affinity, if not 3. Admittedly there are probably practice techniques with the spells that I'm not aware of and I'm not sure how you'd find out without having done a few invokers.

This question might also help Rome make decisions as well as my own understanding, but how much better is the higher intelligence of elves/dark-elves/arials compared to humans in learning Invoker spells?
