Ravenous Scalespawn

This one is very easy. Just use 3 Moths. You only need 2, but you might get super unlucky.

Alpha Strike
Cocoon Strike
Moth Dust

Cocoon Strike first priority, then Moth Dust. Alpha Strike as a filler until next cocoon strike is back.

The usual works as well;
Unborn valkyr
Curse of doom ->
Unholy ascension

then

Ikky
Black claw ->
Flock

And he's super dead

For this and all other battles in Nazjatar I use the same team.
Strategy is also the same for most battles - debuff pet with Valk abilities and try to defeat it with Ikky + Gnome.

[npc=154916] can be found at 29.6 49.7 spot in Nazjatar inside a cave.
