30 Silver Keys are hidden throughout the game. Silver Keys unlock Silver Chests, in which you will find special weapons, armor, and potions. You can also give them to the Demon Door at Necropolis to open it, but since you will lose those keys forever, you should open the Silver Chests first. Search the locations below to find all 30 Silver Keys, which will earn you the achievement “You Are A Super Player.” The game saves every time you pick up a Silver Key, so you do not have to finish the quest you are on, if you only want the key.

Silver Key #2 – When you enter Bowerstone South, search the second floor of the first building to your left to find the second key.
Silver Key #3 – Once you get a fishing rod, return to the Guild, go to the Guild Woods, and find the fishing spot. There is only one. You can fish to find the third key.
