No ballistas or catapults. There are some spears and and javalins lined up and ready to grab.

He grabs a spear but thinks he relies much on his Sacred flame strike

occ: Is it possible to craft a sort of spear thrower (a kind of rudimental ballista) exploiting the local forge? or would it take too much time?

 I'd say that's something that could be done, but would require some downtime. There's not enough time to make it for this attack.

Attack: 25 Damage: 7

 Kriv, your attack roll looks like a crit but when I hoover over it with my mouse is says "18 + 1 = 19". I this case it's actually really important for me to know if it was a crit or not.

I don’t know why it says that. I have a +5 to attack so as far as I know it’s a crit.

Telurion tries to find cover, and prepares to launch a javelin at the dragon once it passes by.

Attack (Game Log): 25

Damage (Game Log): 8

I think we only need Zale's roll for the next fly-over (if Eric indeed uses Sacred Flame).

I am going to use Sacred flame then, it would require just dexterity saving throw DC 13

if hits it would deal 8 damage

Zeminny, hearing the screams of the dying will rush to the parapet to aid. He will find a good piece of cover and rdy his arrow attack

Attack: 18 Damage: Unable to parse dice roll.

Eek would have followed Zeminny. 

Attack with his sling: 19 + 4 = 23 to hit, 4 + 2 = 6 dmg (rolled in game log)

Zale stops in her tracks when she sees the dragon. Fear turns to anger as recognition glints in her eyes. She screams at the dragon, "YOU! I'LL KILL YOU!" Clenching her fists, she looks around for a ranged weapon. Lightning crackles angrily around her throat, but she knows her breath weapon would be useless against the beast. Frantically, she grabs a javelin from the ground. "Grrrrr, I should have bought a crossbow." She throws the javelin at the dragon, then continues to look for a crossbow.

To hit: 15

Damage: 5+2= 7 (Still figuring out the custom rolls in the game log lol)

The Dragon swoops in and kills 1 defender with his breath. He injures 5 of them, including Linan. But this time you are ready for it!

Zale throws the javelin just as Eric Sacred Flame come down. The Dragon avoids them both with ease (nat 20 on the DEX save)

Eek will save you!  Eeeeeeeeek!!

Eek hits Dragon and seems to wound him. Zeminny's arrow also hits. The Dragon seems taken aback giving both Kriv and Telurion a good opening for decent hits.

The Dragon doesn't look hurt, not by a long shot. It does seems surprised though.

((I'll assume the rest of the team is also on the parapet by now))

(Are there any hand crossbows laying around by any chance?)

Perception if needed: 16

(When it gets back around to Kriv.)

Kriv throws a hand axe at the dragon.

Attack: 24 Damage: 6 (rolled in game log because the dice roller sucks)

Zale doesn't find any Hand Crossbows laying around. One of the fallen defenders has a Shortbow.

Fizker comes running up and keeps a Fire Bolt ready.

Telurion throws another javelin!

Attack (Game Log): 15

Damage (Game Log): 9

Zale takes the shortbow and the quiver from the fallen defender. As she does so, she whispers to him, “I will avenge you.” Then she stands up and shoots an arrow at the dragon. (Don’t count on Zale doing to much damage lol. The only ranged weapons she’s proficient in are hand crossbows. Honestly though, I don’t think we are really going to do much to this dragon right now…) 

To hit: 14

Damage: 4+2=6

Looking in the distance you can see the Dragon turning it's head. It lets out a loud roar and... flies away!

Zale, you swear it's a roaring laughter.

(The threat has passed)

“COWARD!” She yells, “You WILL pay for what you’ve done!” She stands there quivering with anger. She growls under her breath, “I will find a way to end you, even if it means the end of me.”
