Thank you so much! I was unsure of the mix going into this (because of crunch) so I'm glad you liked it!
For instruments CSS/CSSS/CSW by Cinematic Studio hard carried. Balkan Ethnic Orchestra by Strezov Sampling, Albion Solstice, and Symphonic Destruction by Heavyocity were great for layering and adding some spice. Requiem Pro by 8dio for some choir stuff (goes on sale regularly for dirt cheap, also learned that this the choir that was used in Dark Souls 2 and 3, and a bit of Elden Ring recently which is cool)
Synths are Vital and Phase Plant, and I didn't go super crazy on FX this time but Rift by Minimal Audio, Subvert by Glitchmachines, Transverb by Destroy FX and Valhalla Supermassive by Valhalla DSP were very handy.
There's definitely more I'm forgetting but this is what I remember off the top of my head

honestly with LASS3 and Cinestrings you might be set for strings, CSS really succeeds in being a great base for layering, being really good at the small handful of articulations it comes with, and working seemlessly with the rest of Cinematic Studio’s libraries. It also has some of the best legatos I’ve heard
Strezov Sampling has some great choirs and “ethnic” stuff
