If you're facing the Everdark Sovereign Gaping Jaw, Adel now starts in his second phase from the get-go. This means most of his attacks are a lot faster, more chaotic, and he has his thunder aftershock attacks.
He will always start the fight with his dive bomb attack.
No More Vomit
Adel's main weakness was poison; it still is. But this time around, he will not vomit when he gets poisoned. This means it's a lot harder to get free damage on him.
Thunder Slam
Adel would sometimes slam his face into the ground, which would be followed by lightning aftershocks like with his dive bomb attack. This time, however, he can also do this 3 times in a row, which makes it a lot harder to dodge since the timings will be different.
Grab Damage
From testing, every time he grabs you, the bleed will go through, even with high resistance against it, meaning the grabs punish a lot more by making you take a lot more damage.
Phase 3
Adel now has an entirely new phase, which I will call phase 3 for understanding. He starts this off between 50%-60% HP and will always start with a yell, after which he will disappear at lightning speed.
He gets new attacks during this phase, is faster, and moves around more. He also gets more resistance and becomes harder to kill.
Triple Lightning Grab
Adel will yell, after which he goes for a lightning speed attack, followed by 2 very fast grab attacks, which can be hard to dodge if you don't reposition yourself. These attacks also do damage around him.
Tornado
This is his most dangerous new attack, and it changes the fight entirely. When Adel wants to, he does his lightning roar, after which he will fly into the air, disappearing. After a delay, he will crash down, which summons a storm. You need to get inside this storm with Spring Steps. If you don't, you will continuously take damage as if you are in the night storm. This makes the fight very tricky since the arena becomes a lot smaller.
