There are twelve Stellazzio coins, plus one hidden coin, to be found in different areas at any point during the game.
This achievement is not missable as the items can be gathered any time.
Take these coins to Treno and offer them to Queen Stella. You will receive a reward for each coin you hand over to her. The prize improves with each coin you hand over, regardless of the order in which you do so.THE 13TH COIN
After you give Queen Stella all twelve Stellazzio coins, speak to her again. This time, she senses that something may be missing. Upon agreeing that something is missing, the Queen charges you with finding the hidden thirteenth Stellazzio coin. To aid you in your quest, she returns all twelve Stellazzio to you, so that you can read the clues inscribed on the backs of each one.
The clues from the twelve Stellazzio are as follows:
"...Through the forest and over the mountain..."
"...by the river..."
"...the cape...the sun was setting into the ocean..."
"...waiting for the sun to set in the ocean..."
"...watching the sunset from the cape..."
"...opposite the direction of the sun..."
"...always looked at his shadow, until one day, he decided to look away. He walked up a hill..."
"...dashed through the night, defying the chilly northern wind that was stinging his right cheek..."
"...ran up a hill toward the sun and fell asleep..."
The clues on the last two Stellazzio coins, Aquarius and Pisces, serve only to wrap up the story.
Assembling the clues, the player can determine that the thirteenth Stellazzio is up a hill above a river, beyond darkness where the sun seems to be setting, somewhere to the northeast.
Thus, if the player leaves Treno, and head northeast to Quan's Dwelling, they'll find the Ophiuchus in the spot where they previously found the Scorpio Stellazzio.
Incidentally, the back of the thirteenth Stellazzio provides the conclusion to the story inscribed on the backs of the other twelve Stellazzio.
Head back to Treno and return the twelve Stellazzio to Queen Stella, plus the Ophiuchus. In return, you receive a Hammer, which can only be equipped by Cinna. THE HAMMER
This item can be used to synthesise the Tin Armour from Hades in Memoria.
If you finish the game with this item in your inventory, there will be an extra scene added to the ending. Better yet, when Cinna comes out in the ending, he will have a hammer in his hand. Great.LOCATIONS OF THE COINSAries
