This week the Writing Excuses team discusses magic again, this time focusing on the cost of magic. Whether or not your magic system has internally-consistent rules your readers can follow (per Sanderson's First Law and last week's 'cast) you need to consider the ramifications of using magic in the worlds you create. Or at least, that's what we think. Have a listen and find out why.

Also, this week Howard attempts to create "Tayler's First Law" using a donkey. It can't have gone too well, since by the end of the podcast he's willing to give the donkey away.
