LotRO calls them “Shouts” and “Cries.”
After the 15th or so it’s just screaming.
Every character appears to have them. Lots of humanoid mobs appear to have them.
If you play LotRO have you noticed how vocal the world is? Everyone is yelling. Goblins in Moria. Captains, Guardians, Wardens. Seemingly everyone.
Wouldn’t it be nice if we could tone it down some?
How about intimidating a mob with self-doubt imposed by “A Stony Regard” or the chilling feeling they’ll have after getting “The Cold Shoulder” from you? Ooh, scary.
Or an aggressive taunt issued via “The Snarky Look” or “A Golf Clap?” (“Gazgar, he mocks you. Attack him!”)
I think I could enjoy a quieter slaying experience.

You’re not the only one. I play with volume turned off to avoid all the yelling.
i love it when people “shout” and someone else goes “shh not so loud”
