So when writing the Plot for my JRPG Extraordinaire, I wanted an overuse of People having their arms cut off in Slow motion. 

I therefore decided that there should be a spell that can replace a cut off arm. However, Such a spell is difficult to perform and renders the caster unconscious for hours. This means that the spell is extremely expensive.

I also thought of ways that you can use this to drive the plot along. For example, let’s take my main protagonist: A young Streetrat-turned Mercenary who hates nobility because he thinks of Them as pompous and Corrupt. However, he has discovered he is of noble blood, but doesn’t return to his clan because of his hatred of nobility. While encountering another important character in the Story, he has his arm cut off. Now he has to put aside his pride and go back to his noble clan if he is to get his arm back, as he’d never be able to get the funds on his own.

How else could this plot element be used?
