Mipha
"The ferry?" Mipha looked in its direction. It had been sitting here, circling the cavern and it wasn't sitting on top of water. Maybe it might actually be safer. She leapt into the air and gave herself a boost with a water jet to land on the deck. She knealt down next to Gatu and began tending to him. "Your wounds are significant, but I will do what I can."
Revali
Revali knew this thing was dangerous, but this...this was lethal. Of course, nothing in this place was without danger, but he's having a hard time believing this is the sage they're looking for.
The range it had was animalistic, wildly unpredictable. There had to be a reason for that. He could feel it, even if he couldn't explain it. That attack was brutal and admittedly shook him up enough to start looking at this creature with a lot more fearful respect.
He'd been trying to study this thing while flying around in the air. It's clear the core is the place to strike it, but the head or more specifically, the eye was also critical. A longer shot to hit, to be sure, but beneficial. It had to be the same way for this newest transformation.
"We can still get this thing! I think we need to put it on ice and cool it down!"
Now to just get its attention. Readying two arrows, he fires them towards the head of Umbrolos.
Umbrolos
Umbrolos continued to strike the ground with the hammer in frustration, leaving pools of pitch in different spots of the island. It roars once again, scanning the ground looking for the archer, but no longer finding his presence. Without his distraction, it refocuses its attention on who remains before it. The first arrow from the Rito fighter missed and struck its shoulder.
Whipping around to face him, two tendrils twist and reshape into two sharp lances to fire at its current attacker. Flying between its two missiles, a second arrow found its home in the creature's head. As before, the tendrils weaken and fall limp and the shadow beast dangles in place, stunned.
Gatu
_Gatu's vision continued to focus in and out. His body felt like lead, but at least he's giving that boss a run for its money with how much damage it has sustained in such a short time. He didn't react too much to outside stimulation as he tries to pull himself back up onto his feet as Redvali came over to move Gatu out of the creature's range with Mipha tailing him, and then moving him over back onto the ferry for treatment. Other than a nice burnt hold in the right side of his tunic, the burn practically cauterized itself on impact; so it wasn't bleeding. But it looked gnarly for sure since it was all sorts of shades of a crusty red and orange with the smelt of burnt flesh._
_As Mipha begins tending to him and treating the wound with her healing powers, Gatu looks to Redvali._
"Red... Take this... Either you... or your twin... put that creature on ice, yeah?"
_Investing the last of his magic, Gatu creates an Ice Arrow for Redvali using the last arrow in his quiver, holding it out for them to take for either them or Revali to shoot Umbrolos with. These kinds of arrows imbued with the power of ice that'll breaks apart on impact, freezing objects in the immediate area, should do the trick since it'll be incredibly effective against hot things- especially the still-burning Umbrolos._
Gatu
_After Redvali takes it, Gatu would pass out and go unconcious- now officially KOed out of the battle. It's up to the others now._
Irina
While the creature is distracted with Gatu, Irina prepares an ice arrow herself. Doing so with a dry arrow is possible for her, but gathering the water around it before freezing it drains her magic much faster. But this is one of the moments when it is justified to do so. Preparing the arrow, she shoots it in the direction of the flaming creature.
Umbrolos
The ice arrow lands right on target at the core of Umbrolos, its body writhing from the pain as steam juts out from the impact and chills the burning pitch where it landed.
Link
Meanwhile, the wolf staggered to its feet. He was very dazed from the last attack. The dark needles had penetrated his fur and he felt a strange force coursing through his body. He feels that some of his life force had been drained in a way that would not be possible to simply heal, at least not with the typical techniques or magics.
Nevertheless, he picks himself up and sees the flames around the monster subside momentarily. He runs towards it and attacks again, this time ready to spring away at the slightest hint that it would begin to ravel itself or change form. He can still feel the intense heat from the flames that were just there.
Redvali
Red takes the offered ice arrow. "I'll put this to good use," he remarked to Gatu. He knew he was unconscious, but still felt it should be said. Taking off, he flies back towards the island, witnessing the shadow beast has already been pelted with one ice arrow. "Guess this would be the perfect time to use this other one..."
Once he was back over the island, he pulled his bow and lined up the shot, striking the opposite side of Umbrolos' body to cool it down.
Revali
"Now that's what I'm talking about! We keep this up and we should take it out no problem!" Revali was glad to see his instincts were right again. Generally, they always were, but it just felt so good to see them validated.
Now that the beast was cooled down, he saw the perfect opportunity to use his most trusted and definitely not problematic bomb arrows.
Besides, had he used them when Umbrolos was hot, they certainly would have been put to waste. But he doesn't have to worry about that now. He takes one out and fires it off at the cooled body, aiming so its explosive shockwave doesn't impact Wolf Link.
Umbrolos
Umbrolos rolls around in pain from the second ice arrow, steam rising from its body and cooling the affected area. Between the two, the heat that once emitted from its body isn't much more than a temperate mist. Exposed in this manner, the wolf can rend and tear at his delight, cooled chunks start to fall from its body, helped along by the explosion that has rocked its body, sending more pieces falling from its form.
Irina
Irina is sick and tired of this gooey thing hurting her and her friends. She joins in to tag team with the wolf again, but this time against Umbrolos instead of the witch. Holding her spear with two hands, she tries to attack the enemy.
Gatu
_Gatu remained prone on his back, unconscious on the ferry, while Mipha works to get Gatu back in the fight or stabilize him with her healing powers. He was going to have difficult time blocking attacks since Umbrolos knocked his Hylian Shield down into the abyss... He might be able to afford a new one with all the Rupees he's been picking up from the slain monsters they've been fighting, maybe even refill his dwindled supplies. But right now; the party had a bigger, blacker, gooey tentacle monster to fry somehow whilst one of their own is down for the count._
Link
Wolf Link’s instincts override whatever pain and ill effects he is feeling. He attacks viciously, learning about his new body and the carnal desire to gnash and bite. An observer might conclude he is enjoying himself with the way he moves. Certainly, this is new territory for him and he fears it as much as he relishes in it.
Umbrolos
Umbrolos wakes up to the pain its in and rapid spins, its tendrils overlapping in successful arcs to push the fighters away so its recovery wouldn't be hampered. The tendrils retract and form together into two arms with crustacean-like claws at the end. No longer taking risks of having approachers, the claws open up wide and lock into place.
Taking aim at the adventurers, the claws snap shut, igniting the air and firing a large ball of fire towards the group. It alternates between arms, firing the other in the same manner, resetting and repeating several times in a hot game of keep-away.
