The Stinger clan is one of three clans that were available to join during the Road to Uberbowl event, requiring completion of Class 4 to join.
Clan Suits & Titles
The Stinger clan, like all clans has 3 different suits to be worn. The first suit, as with all clans, is the only suit available when one first joins the clan, with the other 2 being unlocked as the player gains "Mastery" within the clan. Mastery is earned by wearing the clan's suit while on missions.
There is no required Mastery level for this suit, just being a member of the clan unlocks it.
Hot Shot Suit
The hot shot suit is unlocked when a player earns the Hot Shot title, at 20 Mastery with the clan. If this clan was unlocked in United States of Asura, this suit was unlocked when you get 5900 points.
The master suit is unlocked when a player earns the Grandmaster title, at 50 Mastery with the clan.
The Guru title, unlike the other titles, has no new suit unlocked when earned. The Guru title is earned when one reaches the maximum Mastery level of 99.
As with all event clans, there are 3 pieces of clan gear attainable during the event. All 3 items were available as class rewards (Class 3 for weapon, Class 6 for tool, Class 9 for the armor).
