Gravios’s Rock Shell
Gravios’s body is initially covered in a hard shell, deflecting attacks on its head and wings and causing them to deal less damage on its belly, legs, and back. You’ll need to bring weapons with Blue sharpness to avoid deflects.
Breaking body parts will expose Gravios’ flesh, making the broken body part a weak point.
Frontal Fire Beam
Gravios will stand up fully and raise his wings high in the air, while looking straight at the player before emitting a fire laser directly to its front. This attack has some tracking, so don’t stop moving until it’s out. Sometimes, after firing lasers, a temporary wound can appear on Gravios’ head. Hit with a Focus Strike to deal immense damage and knock it down.
Sideways Fire Beam
Gravios can fire a beam from left to right. This has the same tell as the frontal firebeam, except its head makes a rotating motion before it shoots fire. This attack comes out quick, so be ready to follow it to its right or to time a perfect dodge through it.
If you are having trouble spotting these two fire beam variations, you can always try to dodge left for the initial beam attack, and then right again, if needed, if it’s a sideways fire beam.
Double Fire Beam
Gravios will take a deep breath while moving backwards before emitting a fire laser downwards, and finally upwards again. Gravios will try to re-aim it the second time, so you may need to dodge twice.
Downward Fire Beam
Gravios will assume his fire beam pose, but his head will face straight down this time. It then fires a beam directly beneath it, which causes the floor to explode after a brief delay. This attack usually hits hunters aiming for its belly and legs. Keep an eye out on its head and dodge sideways or back to avoid it.
Leap and Body Smash
Gravios will flap its wings and attempt to fly before smashing its body down. If one of its wings has been broken, this attack will fail, causing a knockdown.
Gas Release
Gravios can release gas with elemental effects directly beneath it. Avoid it by dodging out of the way. The gases it releases can cause fire, poison and sleep.
180 Degree Tail Swipe
Gravios can perform a slow tail swipe that covers a significant distance, similarly to other flying wyverns. A weak spot appears on his tail after the attack.
Tail Sever
Attacking the monster's tail can cause it to sever. This will severely limit the danger of its tails swipe move.
Body Check
If you stay near Gravios long enough, it can go on its side. This is a signal that it’s preparing a hip check. This attack covers its whole body in length, but doesn’t have much reach, so dodge or walk backwards to avoid it.
Charge
Gravios will perform a small roar before charging forward. Due to its immense size, it’s best to stop attacking during it’s standing roar in order to move back and then dodge sideways to avoid this attack.
Charge Into Other Moves
While enraged, Gravios can cancel its charge and instantly perform another move. Keep your guard up, as sometimes there will be no openings in between attacks.
Roll
Gravios will tilt its body upward before rolling to either side. After this attack, it will rest for a short time on the ground, and a temporary wound will appear on its back. Dodge to its front or back to avoid this attack.
Walking Fire Balls - Triple Fireball
Gravios will spit three fire balls aimed at the player while walking forward. The timing is a bit tricky, since the first fireball comes out faster than its other firebeam attacks.
To recognize this attack, watch its wings. If they stay low and near its side instead of high up in the air, this means the fireballs are coming! Dodge fast for the first fireball, and afterwards don’t spam evade, and be patient for the second and third fireball to time your dodges right!
Roar
Gravios can roar after attacks or simply roar by itself. This can create a weak spot on its head, so watch out for this in Focus Mode.
