When the foes reveal themselves, she narrows her eyes at the one being guarded in the back. Spellcaster? she bets by the looks. She unslings her bow, then with glowing fingers, draws an arrow of radiant stardust, sending it soaring over the reptilian ranks and shattering into the figure.
(Guiding Bolt. Sorcerer takes 18 damage. If it survives this round, one attack against it will have advantage next round.)

In the dim light of Stella's dancing lights spell the companions and kobolds clash!
Dieter, the first to notice Sheemish's alarm, spins round and hurls two handaxes at a spellcasting kobold just before the front ranks crash against each other, and the kobold slumps against the tunnel wall, barely keeping its feet.
The front kobolds let loose a cacophony of yipping and jeering that echoes eerily throughout the mine as they make darting dagger attacks at Dieter and Runeson (Dieter takes 6 damage). One kobold is particularly well-armed with shortsword and shield, and manages to score solid hits on both Dieter and Runeson (Dieter takes 7, and Runeson takes 6).
At the same time, spells and arrows fly back and forth through the tunnel. The kobold sorcerer, though wounded, manages to send stinging fiery bolts at Dieter and Runeson (Dieter takes 11 damage, and Runeson takes 7) before Stella puts him down with her shining arrow. Imoen downs another kobold, picking it out from the crowd with an arrow in its eye (Lackey 1 dies).
The two kobolds in the middle rank take a moment to time their attacks. When the spellcasters are revealed, they lift their bows and nock strange red arrows with faintly-glowing runes. Their nature is revealed a moment later, when Stella takes one flaming arrow directly to her abdomen (Stella takes 24 piercing/fire damage). The druidess falls, and so does her spell providing light (Dancing Light spell ends).
Darkness immediately falls over the battle. Calliope also gets hit with a fire arrow, as does Imoen (Calliope takes 10 piercing/fire damage, and Imoen takes 14 piercing/fire damage). Another thunks into Aiwe's shield just as she finishes her spell. With eyes glinting red in the darkness, she releases her spell on the toughest kobold in front, dissonant whispers causing it to flee back down the tunnel.
Some light returns to the battlefield as Calliope summons fey flames onto the two kobold archers. Though the magical fire doesn't burn them, it does nicely light them up as targets (Both fail saves against Faerie Fire, and so grant advantage on attack rolls against them!).
Sheemish lets out a thunderous spell through his gauntlets, trying to force the kobolds back and buy the party some time, but the little lizards are tougher than they appear. Or perhaps the artificer isn't quite back on his game yet...
Commandos 1 + 2 are each granting advantage on attack rolls!
Dragonshield kobold has fled to the middle rank, but because it was forced movement he isn't in a position to put himself between the party and the commandos. So if you can get past lackeys 2 and 3, you can reach the commandos in melee.

"Sister-girl, you have to get up!" Aiwë tosses the arrow aside and pulls Stella to a stand with one muscled arm under the druids slim ones. With her other hand she closes the wound with magic. "We need you! Your story isn't over yet!"

Then the searing pain hits.
"Papa, I think it's spreading!" little Stella says nervously.
She questioned lighting a campfire on top on the Great Oak---even a seven-year-old like Stella could tell you that---but Zenithral was cold and determined to make this a memorable night.
"Hmm? Oh, Snapple Gobs!" the half-elven archer exclaims, turning away from the bedrolls. The Great Oak wouldn't burn easily, but embers were being blown to piles of dried leaves and bark. "Flumphy, go get Halla!" he tells the floating flumph familiar who immediately speeds off.
Zenithral waves his hand a few times, trying to prestidigitate the flames away, but it simply gives way to more. He infuses an arrow with a elemental frost then fires, putting out the main campfire, but it's too late. He slumps his shoulders and sighs in annoyance.
The archer strides over and scoops up his daughter in his arms. "You're alright, Little Star. I've got you. Though your mother's going to kill me for this..." he says chuckling, then leaps off the towering tree.
Stella screams.
Or tries to. Nothing but a raspy groan comes out through ragged breaths.
The white-haired archer swallows and nods, eye-stars regaining their luminance.
"Auroth, strike them down," she hisses in druidic with icy blue eyes. She steps away from Awie then knocks an arrow, an icy dagger forming at the tip. She draws then fires at the glowing reptile that shot her.
Her draw is weak, however, and the arrow pings nigh-harmlessly off its scales and clatters to the ground. Then erupts into shards of ice.
(C1 takes lethal damage, C2 take 6 cold damage if its Dex save bonus is less than +4, Dragonshield takes 6 cold damage.)

(7) + 5 = 12
With one third of the party down, the kobolds try to press the advantage, driving forward with growling yips and calls in Draconic!
Sheemish deflects a fire arrow with one of his gauntlets, then reaches down to touch Dieter's bleeding body, sending a pulse of healing through him. For a moment, Runeson is left the sole defender of the front line, but the paladin doesn't waver or flinch. Two kobolds leap at him, daggers searching for any weakness. Runeson swipes at one with his hammer, sending the kobold skittering back, but its friend darts forward with dagger extended... only to crash against Dieter's tower shield (Dieter's Protection fighting style turns that hit into a miss). The young fighter is back on his feet, and a flash of his sword cuts down the surprised kobold.
Meanwhile, Aiwe works to heal Stella, using a combination of magic and inspiring words to get the silver-haired girl back to her feet, as Calliope sends streams of red flame toward the faerie-fired kobold archers. The kobolds return with a volley of fire-enchanted arrows, hitting Aiwe and Calliope (Aiwe takes 11 piercing/fire damage, and Calliope takes 12 piercing/fire damage). Calliope slumps to the ground, her beautiful feathers marred with blood (Calliope is unconscious and dying!).
But just as one druid falls, the other rises. Stella's arrow of exploding ice kills one kobold commando, and also wounds the other commando and the dragonshield, who is coming to its senses.
Imoen leans against the tunnel wall, clutching at an arrow sticking out of her leg. Then, seeing just one archer remaining, grits through her pain and draws a bead on it. Calliope's lingering magic illuminates a gap in its studded leather armor, and Imoen's arrow finds its mark. The commando jerks at the impact, twists around, and falls dead to the ground.
The dragonshield kobold comes running back to the front line, shortsword diving at Dieter and Runeson (Dieter and Runeson each take 5 piercing damage).
Though there are only two of the enemy remaining, they bare their needle-sharp teeth and keep up the fight. What's worse, with Calliope unconscious the flames of her faerie-fire flicker and dim on the commando corpses, and the tunnel is in darkness once again! (We're in complete darkness now, I believe. If you don't have darkvision, you are considered blind - you have disadvantage on attacks, and attacks against you have advantage.)
