(Of course I roll high for the Will-O', and the attack is on Mist.  You all may take your turns I will most likely not post the next turns until Tuesday night, unless I check before then and everyone has taken their turn.

Kraven squawks again as the ball of light fly's down into the pit and he hears one of his companions scream in pain. Then he will move over to the lip of the pit and fire down into it at the creature.

Shortbow: Attack: 18 Damage: 7

Sneak Attack id I hit: 6

"You coward! Come and fight me!" Gintarou grinds his teeth as he helplessly watches Will-O attack Druquilla. He desperately asks the spell casters of his party. "Zan! Aubric! Do you have any magic that can surely hit the bastard or lure it to me!" 

(Gintarou holds his action and waits the answer from others)

Druquilla draws her shortsword and goes to strike the will-o'-wisp.

Attack: 19 Damage: 5

Kraven's arrow just misses.

Druquilla's arrow just skins the wisp, but you can see that it did some damage.

Zan has nothing to help Gintarou

Seeing his friends being attacked Aubric will search his knowledge for a moment before realizing he doesn't have much he can do at range and will summon the fire to his hands and shoot a Fire Bolt towards the Will'O Wisp

Attack: 10 Damage: 7

"I see… then I have no choice!" Knowing that magic can't solve the problem, Gintarou prepares himself and jumps into the pit. 

DEX:11

Ignoring the damage from falling, the warrior assaults Will-O with the great sword. He pushes his body beyond its limit, his blade moves at a lighting speed. 

Action Surge Great Sword

Attack1: 26 Damage: 10

Attack2: 27 Damage: 17

Yet an other for ball goes flying, Gentarou you take 9 fall damage. However your swings slice through the Will-o' and the light goes out.

Now that there are no threats left what do you do?

Just the moment the Will-o disappears like a candle light in a storm, Gintarou's body collapses on the ground. Gasping for air and moaning in pain, the giant calls to her companions above."Pull up Mist-dono and Druquilla-dono first. I, I can't move. My body hurts everywhere. I need to lie down for a while" He turns his head and asks the skeleton next to him. "You surely don't mind, don't you?"

Second Wind(1D10+2): 11

Mist is unconscious, BTW.

Kraven looks around to see if there are any more threats and then hopefully seeing none, will pull sout his rope and secure it then lower the other end down into the pit so the ones inside can start to climb out.

(Zan has quit, I will puppet him for a little while and then he will most likely choose to stay in the island.)

"Ohhh Mr. Mist are you ok down there?" Healing worlds 9 healing to Mist.

"Huh? Wha...?" Mist groans as he sits up and looks around. "Where'd that bleedin' spirit go? I've got half a mind to give it a piece of my...mind... Ugh. I can't think straight. Somebody get me outta this blasted hole!" He grabs the rope and feebly tries to pull himself up.

If your going to try and climb out it will take a DC12 athletics.

"Take a breather big guy," Druquilla remarks. "You earned it."

Druquilla turns to Mist as he reawakens, "Spirit is gone Gin took care of it. Here let me help you the heat here is hitting both of us hard."

Druquilla will assist Mist in getting out of the hole.

Aubric will assist in pulling his companions from the hole. And as we are all resting for a minute will suddenly drop his head and shake it. "Forgive me everyone in all the excitement I forgot about the stones we found earlier. I have enough for all of us." He will hand a stone to everyone and explain they need to rub these on their bodies for 10 min then make a DC 10 medicine  check. Success and you are fire resistant for 24 hours. 20 or higher and you are fire immune for that time. 

Medicine: 6 

Mist gladly accepts the help and tries to pull himself up the rope.

Athletics: 15

He grunts as he falls back to the floor of the pit and rubs his sore behind as he looks around in frustration.

(How deep is the pit?)

20 feet.
