The Citadel of Chaos

The sorcerer shrieks in horror as you pull out the Jar.
Sensing that this little creature may be a valuable ally,
you open the Jar and release it.
The sorcerer's expression changes to a sly smile and,
as you watch, the little Spider-man advances not towards Balthus Dire,
but towards you!
You must fight it:

As soon as the creature inflicts its first wound on you.

If you defeat it without injury.
