Cursed Ring
"1/2 Sword Damage, Damage taken x2"
The Cursed Ring is a Magical Ring that Link can obtain in Oracle of Seasons and Oracle of Ages. It is a common ring that has the opposite effect of the Green Ring. When worn, the damage dealt by Link is halved and the damage taken from enemies is multiplied by two.
The Cursed Ring is one of the most common rings to encounter. Link can acquire the ring by planting a Gasha Seed and finding it within a Gasha Tree. He can also acquire it in a Seed Ring form by bumping into Maple. Link can also acquire the ring through a Fortune Link at Vasu's jewelry store.
Use
Since the Cursed Ring has completely negative impacts on Link's strength and defense, it could be regarded as a complete useless ring. The only practical use for the Cursed Ring, is to give the player more of a challenge, much like a Three Heart Challenge would do.
