"Remeber, never jump, or run, or attack when you are invisible, for your spell will wear out and you shall surely regret it!"
It is too bad that you forgot your master's words in your moment of indecision. The bandits attack you and leave you for dead. You do however survive. When you wake up severall hours later you are weak and covered in your own blood.
What do you do?
Crawl off bloodily
Wait and hope someone comes around
Put yourself out of your misery and pain
