The Citadel of Chaos

He is not interested in your chat, or your stories,
and questions your authority to be there.
Without warning, he turns into a Snake,
hissing at you, and slithers across the floor towards you.
Meanwhile, the Dog Head on the wall has detached itself
and is now floating through the air towards you.

Will you use a Spell against them ?

or search through your backpack for something to use ?
