Using the Magic Hammer, Link can drive stakes down into the ground. He can use it to pound on other things, too-like enemies! The Magic Hammer can deliver a powerful blow."
The Magic Hammer is a type of Hammer that appears in A Link to the Past and Four Swords Adventures. Although being called a 'magic' hammer, it does not use up Link's Magic Meter in either game it is in.
A Link to the Past
"A Powerful Blow
There are plenty of enemies who can be destroyed by using the Magic Hammer. The only drawback to using it is its range of motion. It's very short."
The Magic Hammer first appears in A Link to the Past. It is found in the Dark Palace and can be used to help defeat that dungeon's boss, the Helmasaur King. It is useful for killing enemies, flipping them over by pounding it on the floor, or penetrating their shells with direct hits. It also works for whacking down "mole heads" and flattening other various things blocking Link's path, such as certain stakes. Its main limitation is its short range.
Four Swords Adventures
The Magic Hammer makes it second and latest appearance in Four Swords Adventures.
