Boss Strike 7: Boss Enforcer Shrow's Raid

Overview
Boss Enforcer Shrow's Raid is the seventh Boss Strike event, re-introducing Shrow and featuring Silver Wolf units scaled to each player's level.

This event also introduced three more new Air units. These Air units were rewarded for completing a certain amount of Tiers during the Boss Strike.

Players had the option to either donate or "FIGHT!" 5-wave formations made up of enemy units, with both options yielding a considerate amount of Boss Points that would be added to the guild's Tier pool.
