Gnome on a rope: 6

(Dex or athletics?).  I’ll roll the d20,

7 plus 1 if dex,   Plus 6 if athletics 

banjo first, then tresvar,   

((Order of climbing, based upon previous posts? ))

1 Banjo - > Dexterity 12  20

2 Tresvar - > Dexterity 21 8

3 Serena - > Dexterity 8

4 Livia - > Dexterity 20

((Ha! came pretty close to your rolls!))

Banjo slides down the rope like a raindrop down a straw. At the bottom he finds a sandy ledge. 

Tresvar comes down next. Her strength makes the climb easy, but her shield catches on the rockwall and sends down a cascade of small rocks. 

As the rocks slide down, Banjo and also Tresvar catch sight of movement among some of the rubble, three giant rats lurk trying to hide themselves. As Tresvar reaches the bottom, they attack - but fail to surprise.

Initiative:

Giant Rats: 14

Banjo: 5

Tresvar: 5

((The other companions would not have seen or have knowledge of the rats yet, so not in initiative, but will assume they would want to help if they could once they become aware, so rolling them as well))

Serena: 5

Livia: 7

“Like sewer rats of waterdeep down here, Tresvar says as she draws her blade on reaching the bottom,  she attempts to get between the rats and Banjo.

The rats attack Tresvar:

Rat 1: bites Tresvar for 3

Rat 2: misses

Rat 3: bites Tresvar for 3

Seeing the grievous wounds inflicted on his dear friend, Banjo has to act.

Drawning his wand, he speaks the calming words to send the rats to sleep.

Roll for sleep HP:  24

All three rats slump into a deep sleep.

(Is Tresvar down?)

”Help!  Get down here!  Tresvar is hurt!”

Banjo will rush to Tresvar’s side.  Is there anything he can do?

Banjo is aware he only has a minute before the rats wake up but he will spend as much time as he can helping, moving on to dispatch the rats before they wake.  

((Tresvar is unconscious from the wounds))

Serena and Livia make it to the ledge, Serena rather quickly.

((Rolled a Nat20 on death save!!! Woot!)) 

Tresvar, regains consciousness. 

Tresvar grabs her sword, stands and shakes her head, looking down at the improbably large gashes in her armor from the rats, while bleeding profusely, and gives a laugh.  “Glad they were on me, and not you!  I had too much faith in my armor it seems.   Thanks for that spell.  Let’s finish these vermin before they wake.”   She  attacks one with her sword.  
19. To hit.    (advantage due to unconscious)  automatic crit damage if hit : 14

"Hey, did you start without us?" Serena says jokingly to Tresvar and Banjo as she gets down on the ledge and sees Tresvar killing a sleeping giant rat. "Well since we have target practice I might as well try out this." She adds and unleashes a beam of crackling green energy towards one of the giant rats.
Eldritch blast:25 Damage:3 "Hey look at that, I woke it up again, oops."

Assuming someone else takes better care of the last giant rats before they can harm anyone she then notices Tresvars wounds. "Ouch, that must have hurt badly Tresvar, better take care of those wounds." She says and tries to help the gold dragonborn with stopping the bleeding. (help action with medicine or just fluff). "Can we go on or should we wait until you regain your strength?" She asks Tresvar in a serious tone when the wounds have been taken care of.

(OOC: Ok, I don´t know why I got the angry red flag but Serena actually just did 3 damage on 2d10 so I guess the giant rat would wake up. I suppose someone would be able to finish the job for her. Sorry about that.) (And now back to normal, weird.)

Once she gets down and sees Tresvar's state, Livia understands just how dangerous this place could be. Even the mighty, armoured figure fell unconscious in two hits. If her protection really works, now is the time to put it up. 
Reaching into her bag, she grabs a hold of her signet ring. She had found it to be a great conductor of her powers, capable of focusing them as she wills. With her other hand, she touches her shoulder. For a brief moment, she is outlined with a bright, white light, which then disappears. Though, even if it is no longer visible, she feels it is still there. Hopefully, it will work.
Letting go of her signet ring from within the backpack and putting the pack on her back, Livia is ready to continue, even if still somewhat startled.

When Serena wakes one of the rats back up, Livia jumps in surprise and quickly takes a few steps backwards, away from the rat.

One Giant Rat is dead, one still asleep, one wounded.

The wounded rat screams with a hiss and tries to flee into the cracks in the cliff wall - ((granting Tresvar an attack of opportunity))

13 to hit with longsword 

8 damage 

With a low growl, Tresvar swings at the fleeing rat.

Two dead. One asleep. Tresvar has her attack action. Banjo on deck.

"Thanks Tresvar, good job, you better skewer that last rat too." Serena says approvingly.

Tresvar stabs the last sleeping rat..

21 to hit

19 damage
