Boxey is going rub her hand and say "Tempus, guide me up these mushrooms, so that I may deliver a whooping to these goblins." 

She attempts to climb once more. 3

Boxey feels she is slipping and curses out loud once more. 

Could you post the order in which we take action? I'm a bit confused.

(Here we go!

Gomphus 20
Boxey 19
Goblins 16
Zerxius 13
Grabius 10
Allure 6)

( 2 fall damage for boxey)

The goblins targeted Allur and Grabius.
Allure:
To hit 8 damage: 5
Grabius
To hit 16 damage: 7

This is embarassing. I guess, I'll die.

Zerxius thinks im tired of this

finishes climbing the mushroom  Acrobatics 20

Then swings his quarterstaff at the closest goblin  Attack: 15 Damage: 9

following up with an elbow on the follow through :Attack: 7 Damage: 4

(Allure is down?)

As Zerxius  kind of pole-vaults up onto the ledge he smacks the first goblin, dropping it off of the ledge, it collapsed in a heap, dead. The other goblin's armor blocked the deadly martial attack.

(Grabius is up!)

Am I able to check if there's another way to get up/around these goblins?

Perception: 4   or   Investigation: 12

Otherwise, I'll get to bounding up the mushrooms. Acrobatics: 9

If I make it to them to attack with my dagger:

Hit: 20  Damage: 7 + Sneak Attack (if Zerxius is within 5ft of it): 1

Yeah, I'm dead, so it mushroom mans turn.

Oh yes, somebody revive me, if possible.

Grabius found a secret door on the side of the rocks. Assuming that he went through it, there was a staircase leading to where the goblins stood. As he reached the last goblin. Sneak attack was possible as Zerxius was close.

Grabius's dagger stabbed into the flesh of the goblin, there was a bit of resistance, but then it tore through, the goblin collapsed on the floor, gasping.

Up on the ledge was a hallway leading deeper into goblin territorry, but everyone except Grabius and Zerxius is on the ground.

(I guess I need a death save Allure)

Gomphus looked around. ~Grabius how did you do that!?~

OOC: I can get there as soon its my turn. 

When it's her turn, Boxey is going over to Allure and will cast cure light wounds 3

"Ugh, thanks. I'll be glad to never have to do that again," Allure groaned as he got up. "Let's never speak of this again. Shall we go?"

Boxey nods and winks. "Not a word." 

while waiting Zerxius inspects the top of the mushroom

Investigation: 12

Allure, still groaning a little, tries to climb up.

Acrobatics: 3

Allure is easily able to reach the top of the ledge.

Zerxius finds that this is the entrance to goblin territory. A huge hall of stone leads deeper. The goblins are also carrying 10 gp each (This will be divided up among the party when you finish this chapter)

"Yeah, let's send someone with armor first, if possible," having been so close to death, tiefling is much more careful.

During her turn, Boxey will cast Cure Light Wounds on herself 10. 

Seeing as how she can't climb up the mushrooms, she is going to search for another way up. Perception: 11

Apparently someone had found a secret door, stairs led to the ledge, anyone could use the stairs. Gomphus waddled over to Allure and reached into his belt. The man withdrew a potion of healing and handed it to the tiefling. ~Gotta stay hydrated!~ Gomphus said proudly.
