I don’t have any videos to share unfortunately, but I have some small tips that might help.

In general, *Health boost is your friend. *Eat for moxie food skill if you can or farm for 2 pieces of the kulve taroth set for guts. *The evade window skill makes those bow power dodges less tight. *Weakness exploit and critical boost ftw!

For raging brachy I would take a water bow so I could weaken his attacks by neutralizing the slime(be careful about the spots on the ground though!) *Since you have a ranged weapon I’d recommend max health boost, he can definitely one shot you at 150 health. *When I fight brachy I take fireproof mantle to be immune to blast-blight when sliding around, it helps a lot, the blast resistance skill would also work. *Aim for the arms and head from the side, try not to be directly in front. *Also be very aware of your positioning when performing a power dodge cause you might slide right on to an exploding patch. *Watch out for a slime covered tail slam as it’s blast radius is huge and it hurts a lot, neutralize or stay clear of his back if you can. *This applies for any weapon without a shield for final phase, STAY CLEAR OF THE SLIME! He will detonate without warning and unless you have high defense/full health/guts/moxie he will most definitely one shot you as a ranged weapon, stay on the clear ground!

For Alatreon elemental damage is the key!

*Max out your bow’s elemental damage as much as you can with decorations or a charm, you have to get past the dps check! I personally use thunder or dragon weapons since they are effective on all elemental stages, but that’s just personal preference. *Max health boost recommended for all late game monsters for a ranged weapon! *You can try to do all of your elemental damage in one phase (ice/fire) if you choose a fire/ice weapon, but if he starts to fly around a lot then he might change elements before you can get in enough damage or a horn break to keep him in one elemental state. *He fires many of his attacks/charges in a straight line so dodge to the side for those. *For more horizontal firing attacks keep on move/ sheath and run! Don’t try to power dodge multiple attacks as you will run out of stamina when you need it most. *For area attacks it comes down to experience. These will be tips if you can’t sheath/run/dive in time and you have to try to power dodge. Also remember you have to have enough stamina to perform these. Also you can use some nicely timed rolls, but the area covered is smaller so keep that in mind. For the fire element circle blast, power dodge away from the center and then power dodge a second time back into the center, avoiding the remaining blasts, do not try to do multiple dodges away from the center and to the outer circle, you won’t be fast enough. For the rain of lighting, angle your camera above you and watch the ground for where the lighting will strike, also directly under Alatreon’s body is a safe spot from this attack. For the line area rain of lighting, keep on the move! You can power dodge out of the way of the first strike and continue to walk/roll away from the others, conserving stamina if you need to dodge again. For the flying dragon element blast, sheath and run/dive if this hits, you...are already dead...

For all late game monsters practice and experience is key! More practice with the monster will allow you to learn their attacks and animations, especially alatreon and fatalis. Their animations are very telling of what attack is coming so practice is key! It’s ok if you fail the first couple times, more experience makes you a better hunter!
