Ash glides down from his perch to claw at the back of the mage's head (the one engaged with Rohan), then back up to the roof a bit further behind cover.

Help action against M1, then fly back (avoiding AoO using Flyby) to the northern roof using his 60' fly speed, 15' north and 10' west of where he had been.  Attempting to achieve full cover, out of sight behind the back slope of the roof.  (The next attack against M1 is at advantage).

Rahza's smile returns as the enemies start to fall. Even with blood trickling down his armor, Rahza's glee seems to completely ignore his earlier burst of rage. He laughs and spins to slice at the soldier beside him (11), but still seems a bit sluggish due to the wound from earlier.

The soldier leans back, avoiding Raia's swing as the glowing sword cuts through air. A barrage of arcane missiles plink helplessly against a shimmering barrier conjured around Aino. Rahza's blade is caught by the soldier's shield as he tries to slash through them.

Near Rohan, Mira is cut down as one of the soldiers manages to slip past her defense, driving his blade through her chest. The Eldorian lets out a gurgled cry before falling quiet, slumping to the ground. Distracted, Jax takes a nasty slash from one of the other soldiers.

The tiefling mage whirls on Rohan, eyes flaring with anger as they use one hand to bat away that blasted owl. Their other hand outstretches, and a gout of flame gushes forth over the scout. (Make a DEX save, taking 14 fire damage on a success, or 7 on a failure).

Worn down from his wounds, Kaleth tries to again to finish off the wounded soldier next to him. But his injuries burn and slow him enough for the Aurellian to dodge his attacks. They try to attack him in return but he whirls the massive greataxe in a circle around him, warding off their attacks.

Aino stares almost rapturously, despite herself, as the mage dies in a burst of fire and thunder on her rapier, almost forgetting to put up the shield against the arcane darts cast in her direction from one of the mages restrained inside her web.  From the corner of her eye, she sees Mira cut down by the three soldiers to the west and north.  Marnoth comes for us all in time...

Coming back to herself, she considers using Marnoth's blessing to teleport to help the beleaguered Jax, but the commander had told them all to hold the gate and he is right here next to Aino, injured and fighting four of the attacking soldiers.  Her voice singsong, a suggestion rather than a command, she calls to Rohan, who she can see, and Karlo, who she cannot, but must be back there somewhere judging from the arrows in flight.

"I will stand with commander Kaleth.  Rohan, Karlo, finish the mages first, I think?  Rohan the one in front of you and Karlo, the ones ensnared in the web.  They are the real danger."  They could burn this outpost down with their magic, she thinks, but does not say.

Aino spends most of her effort drawing the attention of the soldiers in front of her, though she does not go anywhere.  Trying to draw attacks against her instead of Kaleth.  As a result her Booming Blade attack with her rapier, without any help from her owl familiar, goes well awry.

Action:  Rapier with Booming Blade against S8, to hit:  8 (won't bother rolling damage).
Bonus Action:  None
Movement:  None

(Aino's reaction resets).

Seeing Mira get taken out by those Aurellian soliders, Rohan feels fury swell up in his chest. The beast within wishes to be released to exact revenge on the scumbags. But Rohan manages to contain it. This is not the time to lose control. He also hear Aino's voice telling him to focus down the tiefling mage. He turns his head around to shoot her an approving nod, but this distraction is just long enough for Rohan to get buffeted by flames. He attempts to step out of way, trying to avoid the brunt of the spell.

Using this dodge attempt, he shifts on his left leg and propels himself forward in a savage counter-attack. He plunges his shortsword in the wizard's chest, mirroring the fatal blow dealt on Mira. He pulls the blade out and goes for a second (hopefully lethal) strike, as he swipes at the tiefling's throat with his dagger.

Once he's done with his assault, Rohan goes back to a defensive stance, ready to react at the uncoming assault.

Rohan ducks under the fan of flames, still getting singed but avoiding the worst of it(Save Succeeded, take 7 Fire Damage). The tiefling is caught by surprise however, as Rohan comes back up and drives a blade through his chest. The dagger comes next, slicing open his throat and sending him to the ground, gurgling on his own blood.

"KILL HER!" The trapped mage snarls at the soldiers surrounding Aino, still struggling to free herself from the web. Two of the soldiers redouble their efforts to cut through her defenses, but the elf is too nimble, dodging their blades as they arc through the air. 

The other mage near the back manages to break free, moving as quickly as he can to get out of the webbing. 

Two soldiers time their attacks against Raia. While she blocks one, the other drives his sword through the shimmering divine shield surrounding her(DC 10 Concentration Check).

Rahza remains engaged with one of the other soldiers, batting their sword to the side again as they try to land a blow against him.

Near the northern gate, Jax leverages his size and slams down on one of the soldiers with a rage-filled overhand strike, bashing aside the Aurellian's shield and slicing into their shoulder.

The pain rips through Raia's concentration, and the shimmering field falters before failing completely. Gritting her teeth, she turns her blade on the soldier her wounded her.

(A) Longsword Attack: 14 Damage: 7

Which one now?  Ash's sends the telepathic message grumpily into Aino's mind.

Getting his answer, the owl familiar emerges from behind the roof to wing 30' southeast.  He flaps his wings in the face of the mage who just freed himself from Aino's web (M4), taking the help before flying back to alight behind the roof where he started (Flyby, 60' fly speed).

(Next attack against M4 has advantage).

Rahza laughs as he parries a blade and thrusts in response, aiming for the soldier's joint at the shoulder to slide past the armor.

While Raia's attack swings wide again, Rahza finds his mark. The curved blade slips in between the Aurellian soldier's armor, cutting deep and mortally wounded them. While they fall, the owl familiar bursts from hiding again, distracting one of the mages.

Ignoring the tiefling mage falling behind them, all three Aurellian soldiers push forward with their assault on Jax, trying to overwhelm him. The Eldorian parries their blows with in a brief burst of martial prowess, holding his ground.

Kaleth roars, bringing down another one of the soldiers just as it seemed they might finally land a blow on Aino. He whirls on the other soldier, arcing the axe through the air and slicing across their chest. He stumbles forward a few steps from the swing's momentum, leaving an opening for the Aurellian to dart forward and stab the dragonborn in his thigh.

Aino tilts her head to gaze at the mage still trapped in the Web who ordered the soldiers to kill her.  Interesting reciprocity here, as I suggested to Rohan and Karlo that they kill the mages first.  Perhaps we all serve Marnoth in our own way...  I will have to make note in my journal if I survive.

"The Guardian of the Dead waits patiently for us all," she calls out to the restrained enemy mage.  "even you, and even me."

Invoking the reference to Marnoth, she calls upon their blessing (Blessing of the Raven Queen Marnoth), disappearing in a shadowy mist and reappearing as a translucent, ghostly figure just behind the other mage.  The one that had broken free from the web and been distracted by Ash.

Sheathing her blade in booming, shadowy energy, she spins thrusts at her adversary's kidneys with her rapier from an unexpected direction.  Then whirls away to circle back around to the exact spot she started from.

Bonus Action:  Blessing of the Raven Queen Marnoth:  Aino teleports up to 30', in this case 15' north and 10' east, to a spot just NW of M4.  Her form becomes ghostly and translucent, and she gains resistance to all damage until the start of her next turn.

Action:  Aino uses Booming Blade with her rapier to attack M4 with advantage thanks to Ash's help.
To Hit (with advantage):  20 (dirty)
Rapier damage:  7 piercing
Booming Blade secondary damage:  3 thunder IF M4 moves voluntarily before the start of Aino's next turn.

Movement:  Aino spins and circles back around W - W - SW - S - SE to return to the exact spot she started the turn.  Supporting Kaleth and in melee with the S4 and S5.  M4 can use their reaction to make an opportunity attack.

With the enemy mage now taken care of, Rohan can focus back on the trio of soliders harassing Jax. He seems to be holding up his own, but that won’t last. He approaches the wounded Aurellian solider, weapon in each hand still coated with the tiefling’s blood. Using a moment of distraction on the solider’s part, Rohan slashes at his calves with his shortsword, hoping incapacitate him quickly enough to deal the final blow. He follows up with a dagger stab right into the already opened wound.

Movement:

15 feet to the SE of Solider 1

Action (rolled in dice log):

Shortsword attack: 14 (8+6)

Damage (if hit): 9 (5+4)

Bonus action:

Sneak attack damage: 6 (3+3)

Reaction:

Skirmisher: If an enemy finishes its movement within 5 feet of Rohan, he can move up to 15 feet away from them without provoking attacks of opportunity.

Karlo creeps forward just out of the edge of darkness, on that boundary where shadow and light blend. He lifts the ebony bow in his hands, focused on the mage Aino had targeted. Blackish power crackles along the bowstring once more as pulls back, loosing another mote of cursed energy across the outpost. When it impacts it unravels into spindly black ropes that tie around the mage before turning translucent and fading completely. As the hex takes hold, the mage would feel their strength begin to sap from their body...

The archer retreats back into the darkness, eyes gleaming in the dark as he nocks an arrow and sends it hurtling towards the mage.

Movement: 15ft East >> 15ft West
