Fatalis got added to MHW Iceborne last week, after some tries I managed to get some solo kills.
I'd say this is the best iteration of the fatalis fight so far, very frantic.
I still disagree with the nova idea introduced by Behemoth in World, but atleast Fatties didnt top Alatreons in absurdity.
I also dont like that they gave him stun resist, which makes him unreasonable to hammer.
People say that this is to balance against sticky LBG, but in that case they should simply nerf stickies, as those have been overtuned since the beginning.
All in all, a competent "final boss", rewarding appropriatly overpowered gear.
