Wyvern has Dragon Killer?

[Skoal]

I was soloing Sea Puks today outside of Mamool Ja Staging point. I got hit with a few crits and had to super jump. Wyvern then intimidated the mob. I have not seen this before. I rarely solo dragon type mobs and rarely does my wyvern have hate. I had to check the log a few times. I asked a few drg's and they have never seen it before. Is that a common thing and I have just missed out on it?

Edit: Found out in another forum, they do have dragon killer.
