With the ferocity of the sword that hits it, the rat in front of Preston dies on the spot. That leaves only the rat in front of Wulcrath and the wounded one standing before Ella for the group to deal with.

It is now Wulcrath's turn. 

Wulcrath raises his sword again, intending to end this rat RIGHTLY!  Plus, it wouldn't be nice to let the poor thing suffer, even if it IS menacing the party. The Dragonborn brings his blade down on the rodent of unusual size as he slashes at it once more. 
Attack: 14

Damage: 4

Wulcrath's sword grazes the rat, finally drawing some blood. The creature gives a menacing hiss back to the dragonborn, as if promising retaliation in its next turn.

Dracor and Ella, it is time for your turns. 

Dracor would gasp as his firebolt misses its target. Seeing the singed grass near the rat would cause the dragonborn to snarl in frustration. The well dressed Dracor would race forward, moving to the side of his companions as wisps of steam slipped through his teeth. Once he was clear, he would let out a loud roar as an explosion of icy and frost shot forth from his mouth, engulfing the ran and narrowly missing his dragonborn companion..

con 11 save or take 4 cold damage, half on success.

Ella is extremely frustrated with not being able to deal any damage to rats. She growls and swings her mace at the one near her again.

Attack: 14 Damage: 7

Dracor's attack leaves the rat engulfed in ice, thus leaving only one rodent standing. It avoids Ella's mace and bites back at her, dealing another 4 points of damage.

It's Preston's turn, followed by the rest. 

*Would I have been able to get multiple rats without hitting friends?

(In case Dracor’s attack only hits one rat)

Preston turns to face the final rat. With a deft strike, he tries to finish it off and end the battle.

Attack: 22 Damage: 5

And with that, the last of the Giant Rat succumbs to its death. As the dust settles and the chaos subsides, the adventurers can finally catch their breath. The aftermath of the encounter reveals three lifeless rat bodies lying in pools of blood, a fourth charred beyond recognition, and another transformed into an ice sculpture. On the other side, apart from Dracor, none of the party has remained unscathed, with Preston, Wulcrath and Ella sporting bites, scratches, and bloodied wounds.

//with Preston between rat A and rat B, Dracor's attack would have hit him

Dracor would let out a loud roar in frustration as he quickly drew his ornate sword. The dragonborn would then swing hard, smashing the ice covered rat and turning it scattering of red snow.  "ARRGH!" He would shout, breathing heavily. "WORTHLESS!" Dracor fumed as he looked down at the sword and then towards his companions. After a few deep breaths the blood on his sword would start to fade as he muttered a few draconic words under his breath. He would then turn and continue casting Prestidigitation on his companions.. trying his best to remove the blood from their clothes and armor. "I know I messed up earlier... the.. sun was in my eyes..." he would grumble as he glanced towards the scorched grass. The gold and silver scales on the dragonborn continued to fume as steam rolled out from his nostrils as the frost around his mouth and nose quickly dissipated.

Wulcrath doesn't have time to get any more words out as the icy chill blows past him and Preston dispatches the last rat. He's about to snap at Dracor for nearly turning the Paladin into an ice sculpture before the smaller Dragonborn's outburst interrupts him. His expression softens as he sheathes his blade and returns his shield to his pack,  He lets out a tired huff as he feels his adrenaline fade and his wounds start to take their toll. He feels a little faint even, Those Rats were surprisingly tough. Damn things... He hopes he hasn't caught anything...

He moves to be in front of Dracor, trying to see what might be wrong. He finds himself feeling for the other Dragonborn. Perhaps he felt a little indebted to him for his help with the guards...? Either way he makes a limping approach, His Silver eyes flicking to the shattered red ice that now marks where that poor rat used to be. "H-hey, we're all okay friend, no worries. Still breathing." As he looks at Dracor, he tries to figure out what might be wrong, but he's going on nothing here. "First time in a scuffle like that?" He guesses, putting on a little smile that hopefully at least helps the other Dragonborn feel a little better.

He hopes the others are alright as well, but he can't do much for their wounds himself at the moment. He can check on them afterwards regardless.

Dracor would look to the burned patch of grass when the hulking red dragonborn approached. His eyes would squeeze shut and his head would hang lower with every step closer as though we was prepared to be scolded. The slender dragonborn would visibly flinch ever so slightly when Wulcrath began to speak. 

It wasn't until after Dracor realized that he wasn't in trouble that he slowly lifted his head to meet his fellow dragonborn. "Yes... Actually"  He would reply before straightening himself up and trying to stand tall. "I'm just a little frustrated I suppose... Shimmerscale's don't miss or make mistakes." The proud dragonborn would look sad for a moment before shaking his head and forcing a grin. Immediately the dragonborn appeared back to his cocky self. "Next time you guys could try not to block my view." He would say with a grin. "I'll take care of the threats much faster that way... and with less mess." His eyes would look for the cherry colored rat slushy on the ground. 

“It’s all right, Dracor,” Ella says gently. “You were certainly more help in that fight than I was. It’s no matter, though—this is what I’m here for.”

Ella herself is bleeding a fair bit; on a scale of 1 to 12, she looks like about a 3. That doesn’t seem to concern her much, though. She approaches Wulcrath, touching her amulet gently with one hand and reaching up to touch him with the other. She murmurs a brief prayer in Dwarvish, healing him for 8. She’ll then go to Preston and do the same for him for 14 healing.

”That should take care of it,” she says.

"Thanks..." Dracor would reply with a nod. Although he does his best to hide it you can still he seems shaken by the simple miss of his firebolt spell earlier. He moves his fingers and mutters a few words as he quickly removes the blook stains from her clothing. "Should... ahem.. should we head inside the barn then? I suppose it is free of any danger now." 

Preston puts his sword back in its scabbard as the battle ends. He’s not looking particularly satisfied with himself, having let his guard down on several occasions. His wounds are quite painful and he begins to feel sore as the adrenaline comes down. But the important thing is they’re all still standing. The young soldier turns to face his companions. 

He looks in silence at the Dragonborn’s tantrum. Part of him finds this reaction childish. But another part feels that would be disrespectful to someone that just help save his life. Plus, he’s not one to talk when it comes to being temperamental…

"Thank you, everyone. I wouldn’t be standing here right now if you hadn’t come to my rescue.", he says earnestly.

When Ella offers him healing, he gladly accepts and feels already much better. In fact, it’s as if he hadn’t been wounded at all.

"Thank you, Ella. Allow me to repay you in kind."

He extends a gauntleted hand and it begins to glow warmly. He passes it over some of Ella’s wounds and they begin to cauterize painlessly.

(Lay on Hands for 5 points of healing to Ella)

Once everyone is ready to proceed, Preston points at the barn.

"Yes. The barn should be free of danger right now. I didn’t get to investigate much, but I doubt rats this size are a common occurrence around here. There has to be something of notice. What have you found inside?"

Wulcrath nods at the rest of the party's words, letting out a relieved breath as Ella's healing touch closes his wounds, the familiar warmth of healing magic is a boon indeed. Though his smile fades as he notices that Dracor's mood hasn't really improved. Maybe he'll follow up when he has the time...? It shouldn't be too hard to find him if the other Dragonborn is also staying in Meadowhaven for a spell. "Hmm. I suppose I'll meet you in there. The Constable spoke of something interesting before we were menaced by those beastly rodents." Wulcrath makes to return to the Farmhouse to investigate, but not before he takes another look over his companions. "Thank you friends. I suppose I owe you all a debt now hmm?" His eyes move to Ella and Preston to check on them as well. "How are you two holding up?" He asks the Cleric and Paladin.

His expression hardens a little yet as he takes note of the state she's in... He wasn't much of a help during the battle. She looks in a bad way. "Will you be okay?" The red Dragonborn says, tilting his head down a bit at Ella. 

He makes a silent note to himself as well about staying out of the way of Dracor's spells should they fight again with a little nod to himself. Though... hopefully it doesn't come to that.

 Ella exhales in relief as Preston's healing closes some of her own wounds. "Thank you," she says, offering him a smile. "That should more than suffice."

To Wulcrath's question, she smooths her hair and nods. "There's no need to worry," she says. "I'm well. And you owe me nothing."

As you all take a few moments to recuperate after the encounter with the giant rats, you notice that an eerie stillness has descended upon the area. The usual sounds of nature, birds singing, insects buzzing, have all gone silent. Constable Alena is nowhere to be seen or heard. For a moment, it is as if the world has gone mute, but then a gentle breeze rustles the crops and leaves around you.
