Go to the opium seller and attack him slowly. (The idea is to draw out the fight so he has plenty of opportunity to stab you. -- go 3 wary and remove your weapon if necessary)If you're 'lucky' he will sting you with a poisoned syringe. You may now flee, calm, or finish the fight. Find an untouchable on the streets and ASK UNTOUCHABLE HELP.
