The Full Hunt of Crimson Fatalis - Full Hunt GS
So the mod itself is pretty solid. You get to him via hitching post but I highly suggest not doing that and try entering Teostra's nest the normal way to see a surprise. The mod authors kindly put down his hitzones and new weaknesses which is nice. He mostly acts like phase 3 Fatalis moveset wise but he only has 2 phases now. Breaking the horns before phase 2 is still needed because Phase 2 is what literal hell is like without spoiling anything. He also does not do the cone attack anymore meaning you have to make your own opening
The creators say heat proof is a suggestion but this Hunter says its a requirement along with Anti-Blast. If you don't, I imagine it will be like fighting an unholy nightmare between Lunastra and Raging Brachydios.
I've got a few gripes though. The main one gripe I have is his fire gunk attack which he will spam and mashing out is difficult however the hitbox is clean enough that its a 50/50 chance you can roll out without taking damage, but he will stack that shit. Maybe a version where those sparks just create an explosion like the old one I believe would be a good idea as it would be easier to dodge but way less of a pain the ass. A second one is he flies and assuming you can't flash bomb him, you have to wait for his ass to get down, he doesn't fly for long though. He also walks into the lava where you can't reach him so you have to lure him back out repeatedly. Another is that phase 1 is kind've lacking in a way, hell he spends most of it trying to bite me which was annoying but also really easy to exploit, phase 2 makes up for it style wise. This one is minor to me but because of how the area works which is more the fault of capcom than the mod creators is that there a no clutch claw zone above the lava so when turning him you will get magically thrown off so be aware of this, also there is only one place to wallbang him and its at the corner of the map, not the wall the mod creators did.
I recommend to regular difficulty first as the EX one is hard the same way AT Velkana is hard which is it moves like a crackhead and hits harder than it should.
Overall the mod is pretty solid and pretty challenging.
