Icarus, seeing the blade just in time, dives to one side to avoid the attack. He ends up a little dazed from the impact of the ground, but otherwise alright. He immediately turns back towards the summon and archer, trying to distract them from Charlottes attack by making loud screeches and moving straight towards them. His immediate goal would be to temporarily stun the closest summon and move to attack the archer.

The archer doesn't seem to notice Gabriel's escape or Charlotte's advances as it is solely focused on Icarus and screeches back at him, allowing them to carry out their plans. The archer's mangled arm is sliced off by Charlotte's swing and as the dagger pierces its side, it snarls in irritation. Black blood pours from its wounds and as it makes contact with the ground steam rises as the ground clearly becomes tainted black. The archer pulls his longsword out of his summon and imbue it with dark energy as he now swings it Charlotte with the same terrifying strength that he used to decapitate Gabriel's wolves.
Icarus would move toward the summon seeing that it is still up despite all it's injuries. Icarus would attempt to stun the summon by hitting across its neck, but even still it stands. It seems the archer's summons are stronger than the normal undead. The summon then lunges its claws at Icarus' chest

His plan was successful, he is now hidden behind a tree. As much as he would like to help out his companions, he'd only be deadweight without his spells. He also would risk giving away his position if he were to cast something. It would be foolish to do so, he had no other way to defend himself and risk death. Instead, Gabriel would focus on recovering some of his energy and making himself as small and quiet as possible. 

`Gabriel recovers 5 Mana, putting him at 22.5 Mana remaining, capped at 120 Mana.`

Charlotte lets go of her dagger as the blood spills out, then steps back, leaning backwards at the same time. The swing barely misses her nose, hopefully. Not missing the opportunity, the elf springs back up, using her speed to simultaneously swing her arming sword downwards towards the shoulder of the archer's last arm. She couldn't parry the strike in any way, or even take it, even with her armor.

Icarus, making the realization of their endurance, move to do the only thing he can. His aim is to remove the summons limbs from it's body, or remove his spine. He decides the quicker course of action would be to remove a leg or trip the summon, then go for the spine. He backs up, then rushes towards the summon and slides, sinking his claws in right and the summons knee. Worse case scenario, he hoped to carry the leg with him and bring down the summon. Best case scenario, he would remove the bottom half of the leg, the summon would fall, and he'd be perfectly positioned to tear out the summons spine through its back.
Kanesha
Charlotte is able to barely dodge the archer's swing with her quickness and follow through with a swing to the shoulder. As the archer overswung it's arm would be fully exposed and be cleanly sliced from his body. The archer looks down to its two sliced off arms, looks up at Charlotte, back at his arms, and then falls on his knees. 
"Well... This didn't go as planned. Guess this is my defeat. Must say, I thought I had more in me. Liked it better when you were shooting arrows..."
The undead would be too slow to reach Icarus with its claws, and with Icarus' speed he would be able to easily remove the undead's leg, causing it to fall over with its spine in perfect position to be ripped out, but before you can it's body dissipates into black mana. 
"I surrender" The archer says looking at the two of you. "Call over your herbalist friend, wherever he went. I won't continue fighting on the condition that he leaves at least one of the marijuana plants. Fair?"

Not being able to hear the conversation, Gabriel would continue hiding. He might strain his hearing to hear what was going on, but all he can hear is voices. *Better safe than sorry*, he thought as he continues to cower behind the tree.
