Darkhammer

Darkhammer is the mini-boss of the Snowpeak Ruins in.

Strategy
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 a single hit with the Mortal Draw.

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

Trivia
