I’m playing a Mage game, and it has this system where if you fuck up a spell or if non-mages see you casting it there’s a strange paradoxical backlash and reality warps around you in awkward and unsettling ways, like there’s a brief and terrifying rain of bees or you develop temporary coprolalia.

(yes I’m playing World of Darkness oh god don’t judge me)

so Twenty Consequences to Doing Spells Wrong, perhaps, ranging from mildly inconvenient to permanently disfiguring.
