Horn of Winter and Battleshout

[Adam Jensen]

Created a PowerAura for Horn of Winter and I was wondering if there was a way to make it so it doesn't activate if Battleshout is up. My aura for HoW is purposefully annoying so I notice it in the heat of battle, but unless I need runic power, I don't need it if a warrior is providing BS.

Is this possible?

In the Aura Activation, change where it says Horn of Winter to Horn of Winter/Battle Shout
