How to obtain
This material, like all Shiny materials, can only be obtained in two ways:
One is by defeating enemies with White Summons. Given that the Unicorn summon doesn't do any damage to enemies, this effectively means the Saints summon is the only way to acquire Shiny Salts in this manner.
The other is by disassembling equipment (weapons, armor and accessories) which was made with this material. This includes all Prism equipment, which won't be listed below aside from two exceptions as most of them must be forged to acquire.
Items that can be disassembled for Shiny Salt
- Spectral Glove (found in Terra Tower)
- Betta Carotene (found in Terra Tower)
- White Plate (steal from Sky Dragon using Fargo)
- Black Plate (steal from Black Dragon using Fargo)
- Angel Charm
The Angel Charm is the easiest way to acquire this material aside from Summons as it is a common drop from the Myxomycete enemy which can be found in Terra Tower and a portal in the Bend of Time; whereas the others are all missable and only one of each exists per playthrough.
