This is the staff used by the Traveling Wizard on his journeys. It is a powerful staff with a past even older than the wizard who carries it. This item has a past, and there is more to it than meets the eye.
Magic is like alcohol, the more that is used, the more it causes a hangover later on and the less judgement one has when using it. If one waits a while after casting a spell, things "detoxify." A cantrip or two is like a sip of weak beer, whilst a large creation spell is like a bottle of vodka. Cast something too big and you can die from magic intoxication.
