(Uhm? How? I mean I get your characters are super strong and even god-like but like she is surrounded by the power of a god herself I'm not saying you can't pick her up or hit her but I'm saying that they should be hurt or something at least a little unless you are really a god for if you are I apologies because shit Mina is probably dead after this ^^)
((Ah, ok. You could describe what the beasts do to Serenity then (or try to do). 
So you could write - As Serenity reached to grab Mina... (and then say what happened). 
))
Mina was still closing her eyes but she stopped praying since she knew that she wasn't here to kill. Not yet not these people who hadn't attacked her. All she wanted was to protect herself since the feelings in the air were like drugs to her and the hunt was keeping her mind clear.
The tattoos on her skin were each a different beast. From normal hunters to exotic killers she had collected a lot over the years. And each one was capable of taking on a real physical form the stronger Malar's energy inside her the clearer the form. Right now they mostly looked like shadows but that didn't mean they were weak on the contrary while in shadow form the beasts were able to manifest and dissolve as they wished. Claws, teeth, glowing eyes and anything else they could use to attack manifested and dissolved around Mina as they were growling and hissing ready to attack anyone who came too close. Mina wasn't experienced enough to control the hunt completely or else the scene would have looked a lot different but the way it was now these beasts were all emerging together forming a smoke figure with hundreds and thousands of claws, teeth and mouth that were slashing snapping and biting at anything that came close to her.
Like a Blanket, Mina wrapped these beasts around herself to hide the fact that she was scared to hide the fact that her mind was filled with Malar's whispers of death and pain. She wanted to feel secure and to drown in the ecstasy Malar was giving her as the fear, the pain and the smell of blood were filling her. Her own blood. It was just small wounds all over her body since the beasts needed blood to fule their rage to push them into hunting mode. The blood was either hers or her enemies it was the sweet melody of the hunting horn pushing the wild hunt forward.
But at right now she wasn't hunting for pry wasn't running through the woods following the sweet sense of fear and blood she was standing in a cave filled with people she didn't know some of which were powerful enough to make the tattoos on her skin crawl and she had nothing to fight with other than this darkness surrounding her. So she pulled it closer the beasts taking form dissolving taking form again. Serpents, Lions, Tigers, Dragons, Bears and even more gruesome and dangerous animals swirling around her as they appeared and disappeared attacking anything that was getting closer to her.
(I don't know what beasts live in this world so I just wrote down the most common ones but feel free to replace them with any beasts from this world. That'S also why I had trouble describing what is going on because this isn't my world and I can't just go around making up beasts or put animals in this world if they originally don't exist. But just make up the most dangerous beasts in this world and then take a few notches down and those are the ones surrounding her. Like she won't have the end-boss beast tattooed on her like of course not but she is part of the Malar temple so she will have some really powerful ones and on the other hand some kittens as well that just like scratch you and then hiss but just idk it is difficult to explain this power if you know this little about the world since I don't know what I can and can't do but I hope this helps and explains a little and if there is anything in there that makes no sense or doesn't work with this world please let me know.^^)
(I really hope this helps you and I'm sorry it is a little long but I tried my best to discribe the one thing Mina can actually do ~^^~)
In fear, Cate quickly makes her way over to Andrew and Daemon, who turn around. They see chaos in the cavern.
"We need to get out of here..." the witch says. The two men get up and listen to her.
Danivere didn't like the looks of this, and grabs Genii's hand. Looks like Mina was not paying attention.
"Should we leave?" She whispers.
Metalgirl didn’t know what to think of Serenity. But she didn’t want anyone giving her a hard time. Not again. So she was quick to stand beside her against Mina in defense mode.
Genii watched the swirling mass of contorted beasts and blood in terror. He jumped as Danivere took his hand and squeaked out a quick "Yep!"
"... b-but we can't leave Erras." he added, pointing at the Knight who was just stood there staring at the monstrous shadows.
This is exactly why Erras was wary of strangers. He gripped his sword tightly and waited for an opportunity to cut the abomination down.
"GET OUT OF THERE!" Gemma encouraged the others to flee from her position by the cave entrance.
Bellah took Aster's hand in hers and gave it a tug. "We go now." She said, hoping he would follow her away from danger.
Aster was prepared to instil a second bonk but allowed himself to be tugged away from Bellah, he didn't wish for her to be upset as the whole situation seemed to be upsetting her.
Copper yells out to Metalgirl:
Copper: “Lucretia! This party wagon is leaving!”
Metalgirl: “Uh uhhh. I’m staying here to defend ourselves against HER!”
Gets ready to enter Havoc Mode.
Mina frowned her brows as she heard and saw them leave. The worse thing possible was to run away it would only fuel the hunts instincts it needs to rush through the woods following the smell of fear hunt down and kill its prey. But not now not yet she was praying for clarity holding back her instincts fighting against the need to hurt others. She would stay here and hold back until they were gone and then she would let it loose disappear deep into the forest follow the call of the hunt. She didn't want to hurt these people, not after the kindness they had given her. Even those few moments of happily talking with someone were more than she had ever wished for. So she did her best to control to hold back as the blood lust of the hunt grew and more and more cuts appeared on her body. 'Just a little longer' she repeated over and over like a mantra just a little longer and these people would be gone and she would be alone again unleashing the hunt to disappear deep into the forest again. Once again this wasn't the change of destiny a main character like herself deserved.
After Cate briefly explained to Daemon and Andrew what was going on, they nod and extend their hands to the witch. She grabs them and a magic circle envelops them, warping them out of the cavern.
They arrive a few meters outside the cavern entrance.
Danivere takes Genii and sees Erras who looks like he is about to cut Mina down. She takes him along by holding on his cape.
Without his armour Erras didn't weigh much, so he was easy to pull away. He stumbled slightly, but the unexpected motion brought him back to his senses. He took one last look at the dark writhing mass before turning to make a break for it with the others.
Gemma quickly grabbed her old boots off the ground and made a run for it too. As much as she liked Mina, whatever she had become was terrifying.
Bellah led Aster outside and towards Makna. It looked like the land dragon was all saddled up and ready to go.
"Is that everyone?" Genii asked as he reached Cate and the others.
"Well..." Danivere didn't really want to say it, but Serenity was still there. Along with Metalgirl.
"I think Serenity is still in there." Daemon added. "I didn't see her leave. Neither did Lucretia."
After hearing what Dani said:
Copper: "I'm going back for her..."
Metalman: "Hold up Marcus!"
Copper flies back to go get Metalgirl.
(Back at the cave)
Xola: [English Translation] "I would strongly advice evacuating the collapsing cave Lucretia Harper."
Metalgirl: "Not until... she stops..."
Copper flies to the cave and snatches Metalgirl before calling to Serenity:
Copper: "Hey! We have to now! Please, you gotta get outta here!"
Genii watched the entrance to the cave worriedly as Copper flew in to grab Lucretia.
Gemma pulled both her boots on, then stood up and shook Erras. "Come on. Snap out of it." she said to the haunted looking Knight. "Get your map out..." she was already rummaging through Erras' bag looking for it.
"... tell us where we're going." Gemma unfurled the map and pretty much slapped Erras in the face with it.
"... right... yes..." Erras had seen some things, some dark things from his past, which he was still trying to shake off. "I shall..."
"... come on, come on, come on." Genii muttered, still watching out for Marcus and Lucretia.
Copper comes flying back to the group holding Lucretia in his arms.
Copper: "Serenity is still in the cave guys. I think she heard me... don't know if she left."
Pants hard
Serenity snaps out of her battle stance due to Copper's voice. She sees Mina's still busy doing her praying. The cavern also looked like it was on its last legs (or columns).
Serenity retreats, trying to dodge the beasts from Mina's god aura. While she dodges and gets out of the cavern, she bumps against one of the entrance columns and shatters it.
Genii, Gemma and Erras were happy to see Marcus return with Lucretia.
The basalt columns tumbled and blocked the entrance to the cave, sending up a thick grey dust cloud as Serenity got clear.
".... oh yay, Serenity made it." Genii said not so enthusiastically. "Ouf!"
Gemma elbowed Genii. "Gen! She might hear you."
"I was joking obviously." kind of... maybe. Genii rubbed his ribcage.
Erras waved Serenity over.
