Ring of Salia

The Ring of Salia (リングオプサリア Ringu opu Saria) is an item found in TearRing Saga: Utna Heroes Saga. It can be used by Katri in order to transform herself into the Fire Dragon, Neuron. She will revert back to her original form (Sister) after an unspecified number of turns, and it is hence unwise to keep her within enemy range while in her dragon form for too long a period of time.

How to Obtain
Katri has the Ring of Salia in her inventory when she first joins in Map 8.
