In RoS, there's a new legendary amulet called Halcyon's Ascent (original introduction). It's a reference to progressive-house musician deadmau5.

One of the possible powers that can roll on the amulet is:
"When you use Archon, you mesmerize nearby enemies with your skill, causing them to jump uncontrollably for 7 seconds."

The video showcases the amulet's effect and also features deadmau5's song, "Raise Your Weapon" (referenced in the amulet's flavor text).

I think it goes without saying that I do not own the song.

Track: Raise Your Weapon ft. Greta Svabo Bech
Artist: deadmau5
Album: 4x4=12 (2010)

Yep, it's a fun Easter Egg item
