Oh dear, you should have been killed but something has happened to your piggy magic powers and you are able to escape sure and sudden death by magic alone. But it does drain you and it may make things worse...
You decide to...
try casting a magic spell, immediately
rest for a while and then go back exactly where you were (you're in a dangerous situation, you know).
rest a while, but then go somewhere else.
go home and go to bed.
If you refuse to do all those things, then its too late to save you - there's a big green Boogey man behind you and he's going to eat you up and read this book (or use your computer).
