Darkhammer

is the mini-boss of the Snowpeak Ruins in.

Characteristics
Darkhammer will continuously guard his body with his massive Ball and Chain. In order to defeat him, Link must Clawshot a target behind Darkhammer as soon as he starts swinging his weapon. Darkhammer will then pause to pull in his weapon, giving Link the opportunity to attack his exposed tail. Link can also roll behind Darkhammer while he is swinging the Ball and Chain or after his attack lands. Darkhammer can be defeated in two hits with Bomb Arrows, or a single hit with the Mortal Draw.

When defeated, Darkhammer drops his Ball and Chain, which can picked up by Link.

Trivia

 * TPHD:'s armor resembles the suits of armor that line the halls and rooms of the dungeon.
 * The room in which he is fought had an alternative setup as a long hallway with two Clawshot targets, a TPHD:, and five suits of armor. This can be found in the game's files with the ID of Room 49 for Snowpeak Ruins. The final game uses the ID of Room 51.
