As the creature gets closer, in the light of your campfire, Orion and Prim recognize the creature as a wyvern. As far as you know, it is neither resistant to fire nor susceptible to cold, and it is a large dragon; so, I doubt a Web spell wouldn't affect it much.

Prim mentally calculates te distance to nearby trees, to keep from setting the forest ablaze with a fiteball.

"Badger, mind the fire, we don't want to torch the forest, thanks."

(OOC: When you cast the Mage Armor or Shield spells, it isn't reflected in the PC's AC.  I"ve added the Mage Armor and Shield bonuses on Prim's character sheet, but there's no way to say "only whtn these spells are in effect".  Do you want me to erase those and you'll add the bonuses, or is it easier on you to have them there?)

It is easier if you have them there if you plan to cast them prior to every combat. Thanks. :)

Taxidea chuckles.  "Usually it's me who antagonizes the big uglies."  Initiative: 4

"Got it, don't burn the whole forest down."

Taxidea casts "Melf's Minute Meteors" as he waits.

Bolin readies for an attack, holding his action.

Initiative order: Bolin, Prim, Orion, Taxidea, wyvern, Deragor.

Orion tells the rest of the party about the presence of fey beings north of here, in addition to the wyvern.

You're up, Prim.

(sorry)

Prim waits until the creature is within fireball range and out of reach of nearby trees, to cast fireball.  28 pts damage, dex 13 save

Orion holds his action until Wyvern is within range (60 feet), then casts Faerie Fire on the Wyvern.  (all attacks on the wyvern are at advantage)  (It looks like the Prim's Fireball will hit it first)

And Orion uses bonus action to cast Hunter's Mark on the Wyvern.

Alright. Prim's fireball blasts the wyvern, but it keeps on coming, lit up like a shooting star.

Taxidea, you're up, and you have advantage to attack the wyvern.

Taxidea casts a 2nd Level Chromatic Orb (Fire):  Attack: 25 Damage: 20

Then with his bonus action sends 2 of the Melf's Minute Meteors in right behind:  Damage 1:  12  Damage 2:  12   (Dex save DC 14 for 1/2 damage)

Taxidea, did you roll with advantage on that Chromatic Orb attack?

The wyvern takes half damage from both of the meteors before attacking Deragor for 16 hp damage.

Deragor tries to get another arrow off, but the wyvern is too close; so, the arrow misses.

Bolin rushes to Deragor's rescue and attacks the wyvern twice, making good solid hits each time. The wyvern looks to be heavily injured, with one of its wings torn and a big gash down its back.

Prim, you're up, then Orion followed by Taxidea.

Unfortunately yes I did roll with advantage - and a +6 to hit.  6 was the HIGHER roll.  :(

If the Wyvern is in 10 ft of Deragor, 4th level Wither, bloom on Deragor 

9 pts damage (3 hp die)  con 13 save

Orion shoots twice at the Wyvern:

Shot 1: 29 to hit for 12 plus 1 for HM

Shot 2: 20 to hit for 12 plus 1 for HM

The grass beneath the wyvern withers and dies as Prim casts her spell. The wyvern looks beaten as two of Orion's shots hit true. It barely has enough strength left to move. It struggles to take to the air.

Deragor feels revitalized.

Taxidea, you're up.

Orion shouts out, "Finish it, Taxi!"

With primal yelll Taxidea sends another 2 meteors streaking at the Wyvern (Bonus action, Dex Save DC 14 for 1/2 Damage):

#1 Damage: 8

#2 Damage: 7  

Followed by a Firebolt (action):  Attack: 23 Damage: 15

[all attacks are still at advantage, btw]
