The Statue at the bottom of the Dam
The Dam Statue is a large statue of a woman holding a sword at the bottom of the dam. If the player has The Infinity Blade, they may wish to press it into the base of the statue to reveal the Dark Fiend. Siris walks up to the Dark Fiend and reaches out to grab the Vile Shield. However, it grabs Siris's arm and wakes up, releases its grip on the Siris's arm and then fights him. After it is defeated, it drops The Vile Shield, one of the pieces of armor needed to obtain the Holy Band.
Also, if the player taps on the woman's sword while the Dusty Treasure Map is in the player's inventory, you will obtain the Warth (IB2).
