The Citadel of Chaos

The sorcerer is showing signs of mental exhaustion
and is slow to react as you stop behind him.
You notice he is wearing a gold ring with a large ruby set in it
on the index finger of his right hand, which hangs by his side.

You may either try to grab the ring from his finger,

draw your sword quickly,

or search through your backpack for an artefact to use.
