Icarus, just being release, immediately sprints away to put some distance between himself and the archer, running in Gabriels direction. After reaching Gabriel, he turns on his heels and looks back at the Archer. He would stay there for the time being. A dark cloud stars to form around his head, before disappearing, his wounds healed.
Icarus uses Dark Regeneration for 18.75 mana, leaving him with 131.25 Mana, capped at 150.

The archer seemingly smirks seeing you all back away from him. 
"Let's even up the odds"
Dark green energy imbues his sword as he thrusts it into the soil. Seconds later the soil splits in two as decayed hands claw their way to surface followed by a groan. The archer then turns its attention to Gabriel. "Time to receive your reward" Is snarls before running up to melee range of you.

It occurs to Gabriel that maybe this one isn't an undead at all, but rather the master of the undead in this area. He backs up and hides behind the stronger vampire. He doesn't have much choice when his only weapons are a shield and a dagger against a much stronger and faster enemy. A glowing white orb would manifest in Gabriel's hand and is thrown down beneath him to form a translucent dome around him. He chose not to include Icarus in the shield due to the translucent nature of the shield, thinking it would hinder rather than help the vampire.

`Gabriel casts Safety Shield for 10 Mana. He has 17.5 Mana remaining, capped at 120.`

Oh, he wasn't an undead? That was rather lucky. Pulling out her bow while simultaneously sheathing her dagger, Charlotte sheaths her sword with her nocking arm, then readies an arrow. She lets an arrow loose towards the non-undead's chest, aiming to at least not miss. She falls back towards the back while nocking another arrow.

;(Wait, when did that happen
Marie
Icarus hisses at the archer, making sure to stand between it and Gabriel. He knows this time that biting is NOT the way to go, and instead readies his claws to slice up the archer. He nods towards Gabriel, then looks back towards the archer menacingly. He crouches down, and sprints towards it, hoping to run by and deal some damage, specifically at its uninjured arm or head.

The undead that the archer would summon would finally appear fully from the ground and intercept Icarus' charge, using its body as a meat shield as you tear away at its head. The head goes flying but the body remains standing as it attempts to grapple you. 
The archer would take the arrow to the chest and look down and just smirk. It then turns its attention to Icarus and in a cruel fashion it would use its summon as a cover to prevent Icarus from seeing his attack and thrust his sword through the undead in an attempt to also stab Icarus through the chest.

Within the dome, Gabriel would be unable to see what's happening outside clearly enough. He knows that his companions would likely engage the archer, perhaps he is able to use that as cover. Gabriel slowly moves backwards, focusing on the energy in and around his body, and attempt to back up to behind a tree on the opposite end. Best case scenario, the archer and the undead won't see him. Worst case scenario, extra cover against their attacks. He exits the shield, but leaves it up hoping it would fool them long enough for him to hide elsewhere.

They were never required to take all of the samples, but she figures that Gabriel really did want to take all of them, for whatever reason. Charlotte decides that the arrows really weren't working after all. Why hadn't she learnt at least one spell? Cursing her own inept body for having no mana pool(because I spent it all on perks lol), Charlotte sheaths her bow into her quiver again, and takes out her dagger and longsword. She then proceeds to run towards the archer as well to give the vampire support. As the undead-controlling man shoves his sword into the undead and leaves himself open, the elf rushes at him from the side. As she is indeed hard to see, and as the controller is looking at the vampire, Charlotte would probably be able to get somewhat of a clean shot. Maybe. She attempts to cleave her longsword through the man's side diagonally, and cut through the arm that was already mangled, while biting into the chest of the man. She simultaneously shoves her dagger into his side with her other hand.
