Reggie is in the crows nest so he will duck down into it (BA Hide- 16 I don't remember if I should add the D4 or not so here it is anyway. 2)  I take aim at the closest of the Griffons.  firing at it. Attack: 19 Damage: 12 and the D4 from bless 1 If I get sneak attack from my hide 14

 

 I forgot to add the D4 from  bless for the attack, the numbers are the same that they were before, if you want me to reroll the whole set I will.

ROUND 2 (I have time now...)

Benagol aims with the crossbow at the griffins as soon as they get closer (in order not to have disadvantage)

Then drops the crossbow and takes his trusted glaive (Move action)

Attack: 15 Damage: 7

Reggie takes a nice chunk out of griffon 10. Benagol takes aim and will fire at griffon 10 on their movement. 

Griffon 10 moves 80 feet closer to the boat. They are still 80 ft in the air, but Benagol is able to take a shot and it hits! (instead of rolling disadvantage I added 2 AC to the griffon since they were out of range for Benagol). There is a cultist on the back of this griffon that has a crossbow, they will take a shot at one of the sailors manning the ballista. 

Smoking Mirror Hide: Attack: 21 Damage: 5

The bolt hits the sailor and knocks them dead. 2 Sailors and Ardeth remain on the ballista. 

Gerry, you're move!

Round 2 Initiative Order:
Benagol
Griffon 10
Gerry
Griffon 2
Griffon 9
Rubin
Griffon 8
Griffon 12
Griffon 3
Ardeth
Ballista
Crossbow 1-3
Griffon 7
Griffon 5
Reggie
Griffon 11
Griffon 6
Griffon 1
Griffon 4

Gerry will fly towards the griffons as much as possible, sheathing his sword and firing off a salvo of force blasts at the nearest griffon.

Attack: 24(1) Damage: 9 force

Attack: 26(1) Damage: 7 force

Both hit, dealing 4 force damage. Gerry you are within 30 feet of Griffon 10 now, 60 feet in the air from the deck of the boat. 

Griffon 2 will flank Griffon 10. There is not a cultist with a crossbow on this griffon. Griffon 9 will break off formation and fly about 120 ft towards the main mast. Reggie, you get a closer look at what the Griffons are carrying. It seems to be a keg with XXX scrawled on the outside, and the griffon holds one in each claw. There is a cultist with a crossbow on this griffon, and they have a good shot on your Reggie. They are 80 feet in the air, while you are 60 ft in the air in the crow's nest. 

Smoking Mirror Hide: Attack: 21 Damage: 4

Rubin you are up! Griffon 9 is 70 ft in the air above you and to the right. The other two griffons are still a bit of ways away, likely out of range of your hand crossbows. 

Rubin sends 3 shots at the closer of the griffons 

Attack: 16 Damage: 16

Attack: 20 Damage: 15

Attack: 10 Damage: 18

Bless for Rubin's first and second attack
Attack 1: 1
Attack 2: 1

Your first bolt veers just to the left, barely missing the target. But you land the two other bolts into Griffon and they take 32 damage!

Griffon 8 and 12 continue the v formation while Griffon 3 moves to the starboard side of the boat (still 80 ft in the air). This griffon does not have a cultist with a crossbow, but seems to be eyeing the deck looking for a target. 

Ardeth hand begins to emit radiant energy as he casts a guiding bolt at Griffon 10. 

Attack: 10 Damage: 11

The griffon reels as the blast of radiant energy hits their chest. This griffon is looking severally wounded. 

Initiative count 10: ship actions. 

The boat continue to move forward at normal pace. 

The ballista fires at Griffon 10 who barely has enough strength to fly. Attack: 8 Damage: 18

The crossbow on the starboard side has a shot at Griffon 9, they've loaded a grappling bolt and fires! Attack: 18 Damage: 9

The ballista bolt flies by griffon 10, but griffon 9 is hit with a grappling bolt. Athletics check: 7. The griffon is held in place for the moment! They cannot fly anymore. 

Griffon 7 moves with the other griffon, who now have a X formation. Griffon 5 moves to the port side of the boat, eyeing the deck for targets. 

Reggie, you're up!

Reggie is going to take aim on the same griffin as before and fire a bolt at it.Attack: 8 Damage: 14

After Reggie fires the bolt he is going to duck back into the crow's nest and hide. 10

(Griffon 9 is grappled, so you have advantage on the attack.)

Ok 21

Sneak attack damage 17

16 hits, good damage with the sneak attack as well! You shoot this griffon out of the sky with your crossbow. The cultist and the dead griffon fall into the water. The boat is moving full speed, so they are unable to swim to the side of the boat and grab on. Great move!
