Since i still couldn't find any Videos on this and my Plea to include sound design in the Crown Store got no reply, I offer a sample of the animations and the Sound design of the Blessed Highmane Lion. I saw multiple people, myself included, asking for a Sample of how it sounds and since i bought it today i did a quick Video for those yet unsure if they wanna buy it or not.
It has the same Sounds as the Senche Leopard but with a spectral sound effect mixed into it wich is most prominent during Sprints and Jumps. The Animation includes Horns made of light that place themselves on your characters Forehead as well as bright burning eyes. While the Glow around the Lion after pressing space dissipates after a while, the Horns and the burning eyes stay as long as you are mounted.
(This Video is only Available in the ESO Forum and not listed publicly anywhere else. I wish for it to stay this way.)
