At the beginning of Chapter 19 - The Foot of Apollo, you have to push a rock out of the way to continue to the next area. Instead of pushing the rock away attack it with the Lightning of Zeus using the L1 + Square special attack (you must upgrade the Lightning of Zeus to the second level to unlock this special attack). Each attack will give you 4 hits and it will take about 6 minutes to farm 1,000 hits (there are no enemies in the area to break your combo). When you have the 1,000 hits you will get the 'Can't Stop, Won't Stop. BadBoy!' Bronze trophy.
Altogether there are a total of 5 World Weapons in the game. These weapons can be used in combat and each can be picked up at multiple locations throughout the game. When you find ALL 5 weapons you will earn the 'Tools of the Trade' Bronze trophy. Check out the video below to see the location of ALL 5 World Weapons.
Atogether there are a total of 15 Phoenix Feathers in the game. When you find ALL of them you will max out your magic and earn the silver trophy 'Light as a Feather' (every 5 Phoenix Feathers you find will increase your magic). The feathers are in white treasure chests. Once you have found ALL 15 Phoenix Feathers you will then be rewareded with red orbs everytime you open a white chest. Check out the video below to see the location of ALL 15 Phoenix feathers.
Altogether there are a total of 20 Gorgon Eyes to collect in the game. If you find ALL of them you will max out your health and earn the silver trophy 'The Eyes have It'. Whenever you find a Gorgon Eye your health will increase. Once you have found ALL 20 Gorgon Eyes you will then be rewareded with red orbs everytime you open a white chest. Check out the video below to see the location of ALL 20 Gorgon Eyes.
Altogether there is a total of 7 Decayed Chests to collect in the game. If you find ALL of them you will earn the 'If it ain't broke...' Gold trophy. You will need the Amulet of Uroborus (aquired automatically in the beginning of Chapter 13) to reconstruct the decayed chests (stand in front and press L2 + Square). You do not have to loot the chests but dying or restarting checkpoints will mean starting over. If you use 'Chapter Select' you will not get the Gold trophy.
Altogether there is a total of 10 Artifacts to collect in the game. These artifacts are shown as small, white glowing spots on the ground and will unlock special cheats such as infinite Magic. To use the cheats though you must first beat the game. If you collect ALL 10 artifacts you will earn the 'No Drake. You can't have these' Gold trophy. It is possible to get the artifacts via 'Chapter select' and when picked up they are saved immediately. There is no need to reach the next checkpoint. Check out the video below to see each of the artifacts location.
