Shrines over Britannia may get corrupted from time to time. Online players will then get invited to slay the waves of monsters at the corrupted shrine. Once all the creatures are vanquished, a Shrine Boss will spawn. Each shrine will have its own Boss. Shrine Boss will have around 50,000 HP and will yield alot of treasures. Players who managed to do enough damage to the boss to acquire looting rights will also obtain prestige points.
