Monuments (石碑) are scattered around Phantasma in Trails in the Sky the 3rd. By activating them with the Recluse Cube, the party can fully restore their HP and EP for free, buy items with mira, and synthesize quartz with sepith. The Recluse Cube can also teleport the party to any activated monument.
In the center of the Hermit's Garden is the large base monument (拠点・石碑), which allows the party to unseal Sealing Stones to free other characters. Otherwise it has the same functions as the smaller monuments. Items and quartz encountered in the smaller monuments are added to the base monument and can be purchased or synthesized there at any future time.
In Castle Phantasmagoria, there are shadow monuments (影の石碑) (one in each gate) which offer the same functions as the other monuments (restoration, shop, and quartz synthesis), except they glow red and they cannot be warped to.
- Only 17 of these items are available in the Japanese PC release. The Japanese PSP/PS3 and English PC releases add 16 accessories to the shadow monuments.
