Rock Spire Isle

is one of the isles of the Great Sea in.

Features
The island is a long slender island with the path to a Secret Cave being blocked by rocks. To destroy the rocks, Link needs a several Bombs and good timing when throwing them; alternatively, Link can use his ship's Cannon to blow them up from afar. At the end of the path there is a grotto and, inside, Link must use a Boko Stick to light up the room and destroy all the Keese. Once the last one is destroyed, a Treasure Chest will appear containing Treasure Chart 37.

There is a somewhat different kind of Beedle shop around the isle called the Rock Spire Shop Ship, managed by "Beedle's Assistant". Link needs a Wallet upgrade in order to buy most of the Items sold here, which include a Piece of Heart (950 Rupees), Treasure Chart #4 (900 Rupees), and an Empty Bottle (500 Rupees).

Two other Pieces of Heart can be obtained here. One of them is found by taking down two Warships floating around the isles; one of them will drop 100 Rupees, and the other one will leave a Piece of Heart. The second one is found at the bottom of the sea by using Treasure Chart #2 from Windfall Island.
