(GM are Harpies intelligent? Could Jodhr send a message?)

Not the most intelligent 

Jodhr, thinking better of ruining the element of surprise, holds a Fire Bolt ready in his palms. Ready to toss it at the crow's nest once the others are prepared

Narath prepares a Javelin to throw at the rotten Harpy, "Let's not waste words with the beast. I'm ready for a fight!"

Elle prepares his only ranged cantrip.

"As am I! Let's attack before we are discovered."

Narath will whisper a prayer to himself for aid from Tyr and then run out and throw his Javelin:

Initiative: 4

BA: Divine Favor

Action: Javelin against Harpy Attack: 14 Damage: 8 Piercing plus 3 Radiant from Divine Favour.

"Die foul beast!" He screams as he pulls another Javelin.

Oh and on a hit, the Harpy's speed is lowered by 10ft

That hits as you throw the javelin it flies through the hair hitting its wing as it screeches and looks to see where it came from and sees you 

harpy initiative: 20

Elle's Initiative is 13. Do we all get a surprise round?

You do

DC 13 Wisdom or take 5 Necrotic damage

Jodhr init. 

1

Narath can you roll as well?

Post 528 has Narath's Initiative roll

The Harpie let’s out a screech and dives down at Narath with its claws

attack: 5

damage: 6

then tries to swing with its club

attack: 9

damage: : 3

Neither attack hits Narath, he puts away his Javelin and pulls out his Longsword, swinging with gritted teeth:

Longsword Attack: 9 Damage: 11 Slashing and 7 Divine

And saving throw: 12

Initiative order

Harpie: 20

Elle: 13

Narath: 4

Jodhr: 1

Elle is next

Elle runs up to the Harpie and pulls out this shortsword. Channeling his magic he strikes at the Harpie.

True Strike Hit: 12 Damage: 9 Radiant
