Treasure Chart
Treasure Charts are items in The Wind Waker that are used by Link to help him find treasure. Such treasures include Rupees and even Pieces of Heart. The treasure is found by using the Grappling Hook in the Great Sea, at the location shown on the map and marked out by a pillar of light which disappears when Link approaches. There are a total of 41 Treasure Charts, each of which leads to a treasure which, once found, is marked on the Sea Chart.
A total of 31 Treasure Charts are also present in Phantom Hourglass. Like in The Wind Waker, these charts direct Link to underwater treasure, which can be retrieved using the Salvage Arm. The treasure in Phantom Hourglass consists of some Sand of Hours, some parts for Linebeck's ship, or a large amount of rupees.
Oddly, the Treasure Charts in Phantom Hourglass take the appearance of some of the special charts found in The Wind Waker, including Beedle's Chart, the Platform Chart and the Submarine Chart.
