Once you have completed the story of Kingdom Hearts 0.2, a slew of new objectives unlock for you to complete. Additionally, a dozen new treasure chests have found their way into the far reaches of the Dark World, containing relics relating to the twelve zodiac signs. Opening all 12 chests and collecting all 12 relics grants you access to a new mirror in The World Within, with another new challenge hiding within it (see our objective 42 guide for more on that).
Have a look at the screenshots below (particularly at the maps) to find the location of all 12 zodiac relics, broken down by which fragmented world you can find them in.
Castle Town (4 Relics)
Aquarius Relic
Virgo Relic
Aries Relic
Sagittarius Relic
The World Within (5 Relics)
Cancer Relic
Found in the main area with all the mirrors.
Leo Relic
Found in the mines of The World Within.
Libra Relic
Also found in the mines.
Gemini Relic
Found in the endless room of pillars, after Aqua has passed the first two sections of this room. She should be standing the right way up, as per below.
Pisces Relic
Found in the neverending staircase. Look behind Aqua as soon as you enter the first staircase.
Forest of Thorns (2 Relics)
Taurus Relic
Found in the Uncertain Path, right near the beginning in the drop-down where you would usually hop above.
Scorpio Relic
Also found in the Uncertain Path, at the end of the left path at the first fork in the road.
Depths of Darkness (1 Relic)
Capricorn Relic
I haven’t got a screenshot for this one due to in-game sharing restrictions for the the Depths of Darkness, but it’s really simple to find. Make your way to the very end of the Depths of Darkness, to the sandy bit that leads to the final boss at Destiny Islands. There is a pillar to the right, just after the sand begins. The chest containing the final zodiac relic, Capricorn, awaits you atop that pillar.
