Devin and Ebonitus you're up in that order. Ebonitus you also need to make a concentration save to keep your spiritual weapon going!

Devin continues his pattern of attacks on the next barbarian by throwing a Fire Bolt and moving the blue star into it.

Attack: 10 Damage: 5

and as a BA Spiritual Weapon Attack: 27 Damage: 8

As Mullo's swing with her warpick slides harmlessly by Clovis frantically tries to dodge the arc of lightning that follows shortly thereafter (Save DEX DC 13 = 13) 

Ebonitus concentration save (Wis DC10): 18 

 Maintaining his concentration, Ebonitus calmly moves his spiritual Hammer to the next nearest Barbarian (Clovis?) and swings it hard down upon his head.

Spiritual Weapon Attack: 11 Damage: 12 force damage.

Ebonitus does indeed maintain his concentration but it is at the expense of accurate targeting and the spiritual weapon misses.

Alaric swings his Great axe Attack: 13 Damage: 7 at {1-2 = D.O.R.K. or 3-4 = Mullo} (3)

Clovis swings his Great axe Attack: 15 Damage: 7 at {1-2 = D.O.R.K. or 3-4 = Mullo} (4)

D.O.R.K. you're up!

Following a quick glance to the 'wound' left by the greataxe, D.O.R.K tries to surprise Odacer with a stab from the spectral weapon, having at last managed to bring it to the fray. Immediately after, she lunges forward to capitalize on the distraction, striking again for a low blow with the dagger in hopes to bring the man down. 

Bonus Action: Move Celestial Armament moved 20ft closer to main melee, and FINALLY take a swipe at Odacer.
Spirit Weapon - Attack: 12 Damage: 8 Force Damage.

Action: Dagger Strike at Odoacer(if not still alive, aiming for Alaric).
(Melee, Lethal)Dagger - Attack: 14 Damage: 6 non-magical piercing.

As D.O.R.K.'s spiritual weapon slams into Odacer - the barbarian drops to the ground with a groan.

Illezenya, Mullo, Devin and Ebonitus - you're up in that order.

If it ain't broke, don't fix it.

Devin continues to lob fire bolts and slam the blue star into those that are left alive

Attack: 10 Damage: 16

and as a BA Spiritual Weapon Attack: 10 Damage: 6

The death knolls continue as Ilezenya Toll the Dead and uses his spiritual weapon to follow up on an injured barbarian. He keeps to the dark shadows to prevent the humans from seeing him. (DC15 Wis save or take 12 necrotic. Spiritual weapon Attack: 13 Force Damage: 10)

Saving against ringing bells (19)

Ebonitus continues to save his spells for just in case the barbarians start damaging anyone and continues to swing his spiritual hammer at Clovis.

Attack: 27 Damage: 13 force damage

Alaric and Clovis continue to fight for the glory of their tribe:
Alaric -  Attack: 9 Damage: 13 against {D.O.R.K. = 1 & 2 / Mullo = 3 & 4) [2]
Clovis -  Attack: 7 Damage: 9 against {D.O.R.K. = 1 & 2 / Mullo = 3 & 4) [3]

Despite the fact that they were fighting in complete darkeness and no longer had the advantage in numbers Clovis still manages to hit Mullo.

The party gets to act in the following order: D.O.R.K., Illezenya, Mullo, Devin and Ebonitus.

Growing... frustrated in her adversaries resistance, D.O.R.K dropped dagger and removed her shield in favor of pulling forth Helm Splitter, her own greataxe, in preparation of finishing the fight far more swiftly. Though before then, a simple thought sends her spectral spear slamming down for another barbarian like some thin executioner's blade. "Only these few left. Finish the work." She calls out to the party.

Bonus Action: Strike with Celestial Armament at Alaric.
Spirit Weapon - Attack: 26 Damage: 12 Force Damage.

Action: Doff Shield.

Free Action: Draw out and wield Helm Splitter.

From the darkness, the deep chiming sounds continue as Ilezenya Tolls the Dead and keeps his spiritual weapon striking the last few barbarians... (DC15 Wis save or take 18 necrotic damage. Spiritual weapon Attack: 23 Damage: 6)

Devin continues to lob fire bolts and slam the blue star into those opponents that are left alive

Attack: 14 Damage: 12

and as a BA Spiritual Weapon Attack: 14 Damage: 7

Still feeling the power of her raging blood pumping through her veins, Mullo continues to swing her warpick.

Attack: 22 Damage: 11

Another coalesced bolt strikes at the same foe.

Storm aura: DEX DC 13 or take 1 lightning damage, half damage on success

Again the bells of Death roll out and (1-2 = Alaric / 3-4 = Clovis {1} (DC15 [Wis] = 14 and while Alaric manages to shake off the sonorous clanging of the Death bells he is unable to dodge out of the way of Illezenya's spirital weapon and collapses to the ground with a groan.

Mullo concentrates on the remaining barbarian Clovis who (DC 13[Dex] - 21) who in ducking out of the way of the arcing lightning dodges directly into the way of Devin's fire bolts and giant blue star and also falls to the ground unmoving.

So now what!

D.O.R.K spends a few moments more looking over the corpse, and seeming almost lost in thought for a moment. Then following a shake of her head, Helm Splitter is put away, her shield and dagger find their way back respectively stabbed back into place or sheathed at her side. "It is done." She said solemnly, before then looking over and calling to Devin and the rest. "You may approach now... And Devin. I believe apologies perhaps are in order. I did not dare clarify during the fight, least the enemy alter their stratagems, or killed the Shaman, thinking our intent was to take her captive for sinister reasons."

D.O.R.K's eyes than fell back on the bodies. "Not that it seems it would matter... Dawnbringer, if you would ignite." She requests while drawing the blade, hoping to shed more light on the area.

Ebonitus comes forward and surveys the scene, and asks "D.o.R.K., Mullo, have you taken much damage? Would you like some assistance with healing?" Awaiting the answer and performing whatever healing is needed. He then proceeds to advance towards the stone doors to inspect them.
