Part 1: Goblin Arrows

The main passage continues up beyond another set of uneven steps ahead, bending eastward as it goes. A waterfall sounds out from a larger cavern somewhere ahead of you.

You can see a rickety bridge spanning a passage overhead as you round the curve. Beyond the bridge the passage continues curving to the east (right).

As Kama continues around and heads toward the bridge you can hear the sound of water growing louder quickly... too quickly. The passage is suddenly filled with a mighty roar, as a huge surge of rushing water pours down from above!

Order is Kama, followed by Hollow 15 feet behind, followed by Wish and Xora 15 more feet behind, correct? And Wish/Xora have a torch?

Everybody needs to roll a Dexterity save AND a Strength save

In situations like this where someone has to roll a save, would you like me to just roll the saves for everyone? This would save time, but I know a lot of people don't like when people roll the dice for them.

Kama is unable to avoid the flow of water but manages to brace himself against it and is not moved from his spot.
Wish gracefully swims against the current to safety
Hollow is too stunned to move and is caught with the full force of the crashing wave, ending up on her back at the mouth of the cave
Xora easily steps into the room that held the wolves and avoids the wave completely.

Kama can now see a goblin on the bridge, looking down after the flood to see if anyone remains in the cave. He sees Kama and looks like he's getting ready to signal for something, possibly another wave?

Before anyone can react the goblin signals to someone in the room to his left. After that he draws a javelin and throws it down at Kama, missing terribly.

Hollow takes 6 bludgeoning damage from the force of the water

Player initiative now, the goblin has just signaled to another room for something, but you're not sure what it is yet.

The Javelin goes sailing past the goblin's head, missing him by inches as he quickly moves out of the way. The motion of dodging knocks him off balance and he falls off of the bridge, at Kama's feet. He lands awkwardly on his head and his neck makes a sickening cracking sound as it breaks. The goblin is motionless.

Moments after Hollow reaches Kama and the goblin, you hear another wave crashes down the passageway. Expecting it this time, you are all able to make it out of the way.

Now that the goblin is dead, it is totally silent

Everyone gains 10 xp for the death of Bridge Goblin, may he rest in peace

The passage continues to curve around to the east, leading to a set of rough stone steps leading south. To the left of the steps you can see the stream is flowing from the up above. Advancing up the steps you come into a larger cavern.

This cavern is half filled with what used to be two large pools of water, to your left, empty now after they drained them atop you. The cavern extends to the south and east (now your left). It is inhabited by 3 goblins, which are standing by the empty pools. On your right is a passage heading west, apparently toward the rickety bridge. On the far side of the chamber is another set of stairs leading up.

Seeing you climb the steps, the goblins panic. Two of them draw small javelins and another prepares to run toward the steps in the back of the room.

Goblin 1 rushes at Kama, taking a wild stab at him. He appears to score a very solid hit of Kama's chest, but as it begins to press through his armor the spear shatters in his hand. The shock of the spear exploding gives Kama time to swing back, his axe swinging right over the little goblin's head

Goblin 2 throws his javelin at Kama, which misses widely, and then draws a nasty looking little sword.

Goblin 3 makes a break for the stairs, shouting for assistance

Player Turn

Goblin 1 is standing in front of Kama with a broken spear
Goblin 2 is approaching Kama with a sword
Goblin 3 is at the base of the stairs of the other side of the room, about 25 feet from Kama

Also... Seriously? A crit that did 0 damage?
