Your Raid Group has slain the Ubermaus!And you have stopped Mad-Klaw's army, and avoided growing tails.
I'm sure you are disappointed by the last part.As a Tier 2 creature, you receive 18 CSP and 1000 experience that may be applied to any skills.
An equal amount of experience applied to the stats governed by those skills.You will receive a share of loot from the Tier 4 treasure chest that will spawn at dawn on the day following your victory.
