Artemisian Ring

Artemisian Ring is found in Castlevania HD. It works much like the Moonstone, but at an increased effect. During the day, it increases defense by 1. During the night, it is a much increased effect, increasing all of the stats (excluding luck). +6 STR, +5 Def, and +4 for the other stats (CON, INT, MND).

Found on "The One who is Many" on hard difficulty, but possibly on others as well. In a rare items chest or the boss chest.
