After Darkhammer throws his Ball & Chain at you, use quickspins on his tail to quickly defeat him.

1 Cycle with bomb

Originally discovered by sva

By pulling out a bomb at a relatively precise timing window, you can finish off Darkhammer with 1 Jump attack + Quickspin. The position of the bomb is not important, just needs to be close to Darkhammers tail. This is a bit faster than just using the sword.
