3D Dot Game Heroes

You will need to have acquired the Bolt Shield before obtaining the Hero Shield. You will also need one of each color key (green, blue, and red) or the Super Key for this trophy. Before you enter the Dark Tower towards the end of the game, head into the cave just to the west of the tower.

Inside, you will have to avoid several traps, as well as use one of each of the colored keys. In the room with the Magi and the Dark Knights, use the Freeze spell to take out the knights, then wait for the room to thaw and cast Reflect to defeat the Magi. In the final room, you will find a man infront of a treasure chest. Talk to him and answer "yes" when prompted to receive the Hero Shield. The chest behind the man is empty.
