Defeat Ed. Shane Stringer

Overview
This boss fight is a required part of each mastery level for the Secret District Cover Story. You must also complete the silver mastery level of the Cover Story secret district before you are allowed to move on the the silver mastery level of the boss fight.

This boss fight follows the same style as a Boss Fight Event, except with the addition of stamina attacks. Stamina requirements per attack increase at a rate of 5 each time (5  for the first attack, 10  for the second, and so on). The damage done per attack stays the same regardless of the amount of stamina required. As the cost per attack increases so does the amount of experience gained (unlike family boss fights), with a stamina to experience ratio falling randomly between 2.0 and 2.5. Boss Fight Event consumables are used as well as the secret district consumable as the special item. Consumable use does not give experience.
