Soul Ring

The Soul Ring is a Ring-class item coded into.

The ring is not acquirable by any means within the game; it can only be accessed through a hacking device such as an Action Replay. Visually, the Soul Ring resembles a ring with a large yellow jewel in the outline shape of an eyeless Yang symbol.

The Soul Ring, as with most other Rings in The Lost Age, provides no effect when equipped and is instead used as an item to revive a fallen party member to full health with 100% accuracy (effectively emulating the Revive Psynergy or a Water of Life), although there is a chance it might break whenever it is used.

The Soul Ring, usable by all party members, would have been a very valuable Ring: normally, fallen characters can only be revived at a sanctum; while many Djinn are able to revive party members, they rarely are as effective as sanctums (either reviving a character with only a portion of their health or failing completely); and the Revive Psynergy, while effective, requires multiple Djinn to be set and is not available to all classes. There's also the fact that the Soul Ring can be used by any character, regardless of Djinn/class setups, putting it on par with Waters of Life (which one is better is a matter of personal preference).

It is unknown why the Soul Ring was not included in the actual game despite being designed and coded. Incidentally, this is not the only Ring that has been coded into The Lost Age without actually being featured; the other two such Rings are the Aroma Ring and the Rainbow Ring. It is possible that they were meant to be prizes in the slot machines in The Lost Age, since there are exactly three such unimplemented Rings, not to mention similar unused Shirts and Boots. However, the slot machines in The Lost Age instead used the same prizes seen in the previous game, suggesting that Camelot eventually decided to recycle the old prizes rather than introduce new ones.
