More Velkhana locations?

[naga_serpentis]

So, I’ve already beaten the first Velkhana in the Elder’s Trial. I want to forge armor and weapons with it’s parts, but I am unable to because I’m stuck at 10/12 points for it.
Where else can I fight it to grind materials? I’ve searched Google for a few hours with no luck. The only related solution I’ve found is the one I’ve already slayed in Elder’s Trials, but nowhere else.

I am not looking for the egg, I already have the Teostra, Kushala Daora, Bloodbath Diablos, Kirin, Nergigante, and the Velkhana on my team.
