I have it! monk 5/ drunken master 9
Milias Timital, a young and promising monk of the Yellow flower, got curiosity about some fighting stile, known in taverns and bars: The Drunken Master Stile. It's said that such fighting stile was dangerous to learn. Many good monks were lost to alcoholisms, loosing their discipline and training, only good at fighting when they were extremely drunk. But those perils didn't scare Milias, he wished to gain the knowledge of the Drunken Stile, to understood their techniques, because above all, Milias was a monk, a studious and respectful professional of the martial arts, and it was his duty to acquire as many knowledge about the different stiles of fighting he possibly could. He searched masters of this art, and quickly found some of them, rooting in a bar. He tried all to make them teach him, but they just mock of him, and if he dared to defy them, or insult them, after some struggling, Milias was sitting on the floor, with an amazing hurt in his chin. But the young monk didn't give up, he kept trying and trying until one of the Drunken masters, the oldest of them, felt they owe him a favor, since the monk kept them entertained for month!
And so, the masters give him the chance to probe himself worthy. Initially he ended up sleeping after the second mud of ale, or vomiting after the third. But as most poisons do (most addicting poisons that is) alcohol develops addiction and resistance to its sleepy effects.
In the last chance the drunken masters gave him, Milias probed himself worthy, even better than some of the present drunken masters. The others, cheerfully, welcomed him to the "guild of the broken mud".
That should have been all for the studious student of martial arts that wished to learn the techniques of the Drunken masters. But there was little of that student left. Milias became as alcoholic and undisciplined as his masters, and as the years passed, the days of tavern fights (more usual than the days of no tavern fight) made him become a legend among his peers.
The life was good, nothing better to do than drink free, because the tavern owner won anogh gold from the propaganda of having the legendary "Milias, Drunk Dragon" drinking in its bar. But the old tavern man died of advanced age after a few years, and Milias found himself in the streets, with no money left to spend on drinks, or anything else! "Milias... you must earn some gold ye know? How! How?!" he used to say, walking funny through the roads of Varisia. "Ye could fight ye know?" he asked himself after some months. "Aye! Tha's what I'm gonna do, fight! After all I'm the Drunken lizard right? No wait... it was the drunken lizardman, that's it!"
With that in mind he quickly found a group of adventurers that could pay for his vice as long as he fouth by their side.
