One by one every single tank in their large group charged up to the colossal beast. All of the players in her group, except for one, told her they were not going to die. She wasn't expecting responses...but they were appreciated. Arina watched from the not so far off distance. That was another class that she highly respected. The fact that some players will just throw themselves in front of an enemy and take and block every hit to the best of their abilities just so they can hold a boss on themselves to protect their teammates. 
Well..now she felt selfish for player as a DPS class. They were all about damage. 

Arina actually lightly slapped herself across her face to get herself back into the action. She needed to take pride in her class choice. So with that newfound pride coursing through her she drew another arrow and let it fly at the beast. It struck and the arrow stuck in his huge disembodied and chained face. 
She let another arrow fly, and then another. With all the arrows hitting relatively the same spot: The monster's face. She saw one of her arrows fly right over his head and she cursed herself as she missed. Arina then activated a skill of hers and her bow started to glow light. She didn't pull an arrow back but instead the skill put a bright purple arrow on the drawback for her. Once she released it the skill activated and she was able to release five more arrows just like the first one in rapid succession. The arrows and streamed over the heads of the many tanks and warrior DPS builds and hit their target. 

The hulking mass of bodies that were each emitting their own low groans let out a loud bellow that seemed to stagger a few of the weaker classes back. Arina almost fell back but she was able to catch herself. 
The boss moved back a bit and focused his attention down on the various tanks that were in front of him, like he had been doing. He had tank and DPS characters all around him
The boss started to swing his cleaver anywhere at the ground as he was trying to hit whichever player was drawing his aggro. After a second or two the AI shifted its focus to what appeared to be the smallest tank on the battlefield. The mass of bodies raised his cleaver and swung it in an arc to not only hit the one drawing his aggro but the players around Fuyuko. Two tanks standing near Fuyuko were not anticipating the attack and were knocked back by the sheer force of the cleaver.

One of those tanks couldn't take it and his health dropped to zero and he left behind his flame for a revival when it was ready. The other tank was knocked to her feet but almost immediately she was covered with a soothing green aura and her HP bar shot back up. The healers were certainly having their work cut out for them. 
With a player killed the boss seemed to let out a laugh as his AI recognized it had killed a player. The boss then had another player draw his aggro. A DPS character of all things. 
Arina saw this from a distance. That must have been impressive damage to draw the boss's aggro away from a tank. The disguting mass of deformed bodies solely turned his attention to this DPS player. She looked so insignificant to him. His AI kept repeating the program to kill this player, so he would do. In that moment he raised his cleaver for a direct downward swipe. With his cleaver raised Arina knew exactly what was going to happen. 

And the member he was going to attack was part of her group. She had one idea to try, she had no idea if it would work but she was going to try it. Time seemed to freeze as she drew her bowstring back with no arrow. She activated a skill and a light green arrow with a large front appeared in the vacant place. She took a deep breath and then let it fly. 
The arrow penetrated deep into the monster's arm, just like she planned. Then it exploded, causing a few of monster's body parts from his cleaver holding arm to fly off and burst into the sparkles. He stopped his attack as he was staggered slightly. 
How she had managed to do that she had no idea...
Arina was sure all of her group members had done way more impressive things. That wasn't anything. The boss's health was dropping significantly. Just a few more moments and he would fall. Arina hoped.

But..now. The boss brought his arm out and in a low groan he repaired his arm with more body parts. Just at that moment a tank around his many feet struck him and caused his aggro to switch. That DPS character did not go unnoticed. 
This monster then threw his cleaver all the way to the other side of the room away from the players and it collided with the wall with a loud bang. 
[b]"Alright!"[/b] That same tank leader yelled so everyone could hear him. [b]"We've got him down to his changing attack pattern, that means we-.."[/b]
The tank stopped talking as he watched the boss bring his arms into his center and started to charge up a burst of dark magic. His eyes went wide and he started to two hand his shield. 
This attack was not supposed to happen yet! His HP wasn't low enough. [b]"Tanks raise your shields! Go! Go! Raise them! DPS! Get away!"[/b] The word for tanks to raise their shields traveled all around the boss as every tank started to scream it as loud as they could. 

Arina had no idea what was going on. She had an arrow ready but the boss was just..charging something. The healers all had spells ready for whatever was coming. 
The Boss then finished charging his attack and let it loose. A large surging pulse of dark energy came from his core and covered a wide area. Effectively knocking back any player who wasn't prepared for the attack. 
His attack patterns were now going to be different as he had no cleaver. The two other leaders of the group were both watching in awe as they had never witnessed that attack that early.
