Stalwart Vah Anima Cuirass :: Recipe

In each of these, Pattern for Vah Shir Tunics, Vah Shir Needle, and Water Flask are constant. Each uses an increasing quality of Filament, Leather Tunic Template, Marrow, and Ancestral Acrylia Thread. Based on this, I conducted the following searches to conclude the most plausible ingredients for this level of Vah Anima Cuirass:
Search: Filament
https://everquest.allakhazam.com/search.html?q=Filament
Search: Leather Tunic Template
hhttps://everquest.allakhazam.com/search.html?q=Leather+Tunic+Template
Search: Marrow
https://everquest.allakhazam.com/search.html?q=Marrow
Search: Ancestral Acrylia Thread
https://everquest.allakhazam.com/search.html?q=Ancestral+Acrylia+Thread
It is possible that, rather than Indurate Ancestral Acrylia Thread, Refractory " " " is used, but based on the revel requirement tags on the two, as well as the previous recipes' threads, it should be the Indurate " " ".
