Do you have the other one, I think it's Guard+ or Super Guard or something? THere's two guard traits, and one of them allows for guarding normally unguardable moves like Vaal Hazak death ray.
Yeah, that's Guard Up, and I did bring it, else I probably wouldn't have been able to block some of the breath attacks. As a rule I never run any shield-centric weapon without both Guard Up and Guard 5.
In other news, I'm back after beating Fatalis a few times with a friend. My suggestions to anyone who plans on fighting it are as follows:
- Don't depend on a shield. Just... don't. You might be able to survive, but the constant knockback will make doing enough damage to kill Fatalis within the time limit nigh impossible.
- DO bring Heavy Artillery 2. If you have it, and you're hitting a softened chest with the Roaming Ballista (the machine gun), you deal like 70-something damage per shot, and the thing has 100 shots. That's 6000-7000 HP shaved off in like 20 seconds. Use. It.
- Enter the arena with the Ghillie Mantle on and use the cannons (WITH HEAVY ARTILLERY 2) for a free knockdown at the start. I won't go into details on this; it's easy to look up a YouTube video to see how to do it, or to just experiment and figure it out yourself.
- Consider Fortify. Nobody wants to get carted, but it'll probably happen. Having a considerable percent boost to attack and defense each time you cart makes up for the DPS loss of having to schlep your way back to the arena, and might just save the run. Plus, it's super easy to get via decoration.
- You kinda have to build a set for it, but one of the best weapon options for this fight is Switch Axe, specifically spamming Zero Sum Discharge with Rocksteady and Temporal mantles. There are also a few moves in Fatalis' arsenal where it's safe to cling to its face even though it's actively breathing fire. You can get a free ZSD during these openings, and you want to get head breaks anyway, because they A) get you materials, B) weaken Fatalis' flame breath, and C) provide a lengthy knockdown for more damage.
- Another good option if you're playing with multiple people is Sword and Shield with a support/damage build. It's not too difficult to get Wide Range 5, Speed Eating 3 and Free Meal 3 along with lots of damage skills, and if you're not aware, Sword and Shield is
broken strong in Iceborne.
As an aside: Sword and Shield's Perfect Rush has motion values that look like this: 45 + 45 + 60 + 55 + 65 + 70. That's 340 total motion value. For reference, the Greatsword's True Charged Slash (Power) has a total MV of 286. Yes, Sword and Shield can deal as much, if not more damage than Greatsword in roughly the same amount of time. On top of having very fast attacks and being able to chug potions to heal friends at a moment's notice. Capcom has truly forgotten what balance is.In terms of how I feel about the fight after beating it... it's okay. Fatalis' attacks felt really unfair at first, but after enough practice it became apparent that there was a pretty reliable way to avoid basically everything. HOWEVER, I do feel like the overabundance of fire breath attacks makes it hard to tell which one it's doing sometimes, which occasionally led to my death as I dodged at the wrong time and instantly lost all my HP.
I think the fight would be 1000% better if you had the usual 50 minutes instead of 30. Fatalis already wastes 2 of those 30 minutes just doing unpunishable cinematic BS, which means it's actually a 28 minute fight, and more of that can easily disappear as it decides to slither across the arena while becoming a giant hitbox. Once you have the monster moveset down (which will take any number of attempts, but you'll probably get there) it starts to feel like you're fighting a timer instead of a monster. I've always hated DPS-dependent fights, and I don't know why Capcom has had such an obsession with adding DPS checks to Monster Hunter since World; fights like this encourage a boring damage-centric meta and discourage people who want to use more eccentric and creative builds from playing the way they want to, which is silly in a game with so many weapon options and armor skills.
In short, there are some questionable design decisions, but it's suitably difficult as a true final boss.
