Light Ring L-1
"Sword beams at -2 Hearts"
The Light Ring L-1 is a Magical Ring that Link acquires in Oracle of Ages. There is no possible way to acquire the ring in Oracle of Seasons directly, but it can be acquired through a Linked Game by using the Ring Secret.
In Oracle of Ages Link can acquire the ring by heading to Nuun Highlands while he has one of the three Animal Companions. If Link has Ricky, he is able to obtain the Ring by jumping on top of the higher area and entering the cave where the ring is.
With Moosh, Link is able to get there by flying over the pits and entering the cave on the east corner of the area.
With Dimitri, Link has to swim in the water on Dimitri to the waterfall on the east side of the area. After swimming up it, Link is able to find the ring.
An upgrade to this ring can be found in Oracle of Ages in the form of the Light Ring L-2. This item allows Link to shoot Sword Beams if he is missing up to three hearts, instead of just two.
