The arrow speeds forward and hits bones. It sticks in and the creature doesn't seem affected in the least. 

The creature rears up and you can see the reptilian head of a dragon coming into the dim light. Black rotten skins and scales fall of as it moves. It is of medium size but looms.

(By saying it doesn't seem affected, do you mean it seems to heal all damage and we need silver or magic to damage it?)

(lol. No it doesn't take pain like a normal creature. It s undead and though you know about it you have never seen one. 😉) 

(whew)

(I'll move Arric and the creature. Then the others can make their moves.) 

Arric moves forward, passes Hoyle and waits for the creature arrives readying his action. As the creature's head swings down the corridor Arric smashes down his morningstar. Attack: 22 Damage: 5

The dragon's head takes the hit but comes back quickly to spew acid down the corridor. 

OOC:( Those in the corridor ( I think that it is everyone )  take 6 acide damage, half if Dex sav DC 11 )

Dex save: 13 

As Joshua runs back to try and get out of the corridor (staying put if close enough to take AoO) he shouts words of healing to heal 6 to whoever is highest on the prioty order and failed the dex save, if no one failed Joshua holds action to cast it on the next person who gets attacked.

Prioirty Order: Talon, Tait, Aric, Hoyle, Klaus

(Dex save roll for Tait)

13

Talon would skitter backwards, extending a feathered hand towards the skeletal dragon. "AAAHHHHHHHH!!!" He would scream in the voice of a little girl while casting guiding bolt, sending a burst of white light screaming towards the creature.

Attack: 10 Damage: 17 radiant damage

DEX save: 19

Talon scream shatters the silence. 

The radiant bolt that streaks down the corridor misses the creature but sheds light in passing into the room in the back. It's filled with trashed books and junk from an ancient laboratory. 

(OOC: Who is missing ? I ll make the moves then you can go again.) 

(OOC: not sure)

(OOC: Talon needs a dex save still, Tait and Hoyle need action. Klaus/Arric need everything. And then monster again)

(I am at the bottom of the initiative order and was waiting for my turn, but I can go now.)

So here we go. 

Save for Arric is 11

Klaus goes to the front next to Arric to protect him from the creature and attacks Attack: 24 Damage: 11

The dragon takes a mighty blow on the side of its maw and falls to the ground. It is not out of the fight yet but the damages are pilling up.

• Tait and Joshua can move.
• Then Hoyle and Arric. 

Is there space for Joshua to move past the monster, to be behind it?

Tait moves so that he can get a clear line of sight at the creature and casts firebolt.

Attack roll

18

Damage roll

10

(The attack roll is a natural 20, so does that bump the damage up to a whooping 2?)

 That would indeed be a critical damage

 Yes there would but roll a Stealth (if you haven't already)
