Does Ashen Hallow ever "Pulse"?

Super random, but I was in Oribos and I saw someone (I’m assuming a Paladin), drop a giant red circle on the ground that looked just like Ashen Hallow, except it was pulsing/throbbing/rippling from the center to the edge. I have no idea what it was and I was telling my guildies about it and they all think I’m insane. Does anyone know what this could have been? I had a pally friend test Ashen with the leggo and that wasn’t what it was…I am in search of answers.
