An Aragami resembling a human fused with a butterfly. Emits rays of light from its forehead: baffles God Eaters as it floats seductively through the sky. Thought to have first appeared along the Mediterranean coast. hard to inflict serious damage while in mid-air, so shoot it down, then attack it with one's sword. Launches long-distance homing attacks as well as debuff attacks, so take advantage of the terrain and stay mobile.
Pierce/Short Blades: Difficult weapon to use against Sariel. You can either try to enter Burst Mode and attack the head using double jump and aerial attacks or you can wait till it's enraged and attack the legs. You can also target the unbound skirt, which becomes weak to pierce attacks but hardens whenever Sariel is enraged. Fighting Sariel near an elevated plane or activating the Mid-Air Jump Skill will make the battle easier whenever you are using Short Blades.
Sunder/Long Blades: Try to get into Burst Mode as soon as possible to gain access to your double jump. Once this is achieved, focus your attacks on the head by using double jump followed by an aerial triangle attack. Shift your attacks to the legs once Sariel becomes enraged as they will become very weak to sunder attacks. Fighting Sariel near an elevated plane or activating the Mid-Air Jump Skill will make targeting the head easier.
Crush/Buster Blades: The best blade type to use against Sariel. Position yourself properly by backing up a little, then attack the skirt using the Buster Blade's aerial square or Charge Crush multiple times until it's down. Wrong positioning will end up in failure as your attack will incorrectly hit the legs or the arms. Once it's downed, unbound the head using Charge Crush to give your snipers an extra target for shot/laser bullets. You can also attack any other part other than the arms until it gets up. Rinse and repeat this attack process until it dies. When Sariel becomes enraged, shift your attacks to the legs as it will become weak against melee attacks.
Elemental:Elemental weapons other than divine are slightly effective against Sariel's head, torso and skirt. Don't use divine blades against Sariel.
Regardless of the blade type you are using, always position yourself near of under Sariel and lure it to use its melee attacks before attacking with your blade. Sariel's long range attacks are faster and deadlier as compared to its melee attacks so stick close to it at all times if possible.
Melee attacks on a Sariel are only effective when it's downed. To inflict Down on Sariel, you need to attack the skirt (using melee crush or bomb/radial bullet attacks) and/or the torso (using shot/laser bullets).
Pierce/Assault and Sniper Gun: The unbound head is the only part where shot/laser bullets are effective and can be easily aimed with HDH. The torso is also weak against shot/laser bullets but it can only be aimed whenever Sariel raises its arms and skirt to use its long duration light pillar attack. Shooting the torso consecutively will inflict Down on Sariel. Once Sariel becomes enraged, the head will become extremely weak to pierce type bullets regardless if it is unbound or not.
Crush/Blast Gun: The better gun type to use against Sariel. Your role is to focus your bomb/radial bullets on the skirt to inflict Down on Sariel and make it very susceptible to melee attacks for the entire team. But watch out as the skirt hardens whenever Sariel becomes enraged.
Elemental: You can use any elemental bullet on Sariel other than divine bullets.
Wait for Sariel to use a melee attack with a long animation before positioning yourself at mid-range and shooting it with your bullets. Never snipe a Sariel at long range as its laser beam attacks will overwhelm you before you can even shoot.
Head: The fastest way to unbound this is to use homing pierce bullets such as HDH. Another way is to use the Long Blade's aerial triangle attack. Otherwise, you will have to wait until Sariel is downed and all blade attacks can reach its head. Another way to unbound this part faster is to wait for Sariel to be enraged then shoot its head with shot/laser type bullets with any kind of elemental attribute other than divine.
Both Legs: Wait for Sariel to be enraged before attacking this part with any type of blade.
Skirt: The fastest way to unbound this part is to shoot bomb/radial bullets on it with any kind of element other than divine. Another way is to use Buster Blade's aerial square attack or Charge Crush. This method requires some proper distancing, timing and practice before it can be done. The final way is to wait for Sariel to be downed then attack with this part relentlessly using any kind of blade.
