Anyway to decrease attack speed?

I'm currently running glacial hammer. I enjoy the slow but rhythmic "hit and reposition" style until I got a lot of attack speed from an ascendancy node.

That extra dps is obviously nice but it completely destroys the rhythm. So is there a way to decrease my attack speed in a non-detrimental way? Only thing I can think of is the pulverise support gem which doesn't help glacial hammer.

The Warden's Brand unique ring may do the trick if you are using 1-handed and/or don't mind losing DPS:



Other than that you may need to change weapons to one with lower base attack speed like Marohi Erqi or Trypanon, although you generally need a specialized build for Trypanon.

EDIT: Nearly forgot, if you're a block build then The Anvil will also take your attack speed down a notch on exchange for nice defence:
