Grabius will also slink away from the mushroom and he always is on the lookout for a sneaky way around. I will also look for any traps as we get closer. 

Perception: 7

investigation: 16

You identify no more traps, but you realize the mushroom has been intentionally placed. It seems that getting close to the gate requires you to first get within 30 feet of the shrieker.

::Hey, Gomphus! Do you think you can do anything to help us get past the mushroom?:: Allure asks, as he swings his tail in irritation.

Boxey tilts her chin. "We could try to hit it with some magic. It might set off the alarm, but we could keep ourselves hidden and ambush any goblins who come outside. If all else fails, we place Gomphus there in the mushroom's place." 

"I can do that, I would just like to wait and see what Gomphus has to offer," Allure answers.

Gomphus shrugged.  It then occured to boxey (due to the nature check) that a shrieker is a bit flimsy, and will not be able to shriek if it is dead. Killing it should silence it.

Boxey cracks her knuckles. "If we kill the mushroom, it won't make noise."

"In that case... Glacius!"

This time allure did not call upon the granted power, but innate. Shard of ice, created by Ice Knife flew towards the mushroom.

Attack: 14

In case shard of Ice hits (we don't know AC) it deals 7 piercing damage.

Hit or miss, it explodes, dealing 9 cold damage to everyone in 5 foot radius on a failed DEX save DC 10.

The mushroom will make the save with disadvantage, because, first of all, it's unaware of out presence, and secondly, **** it. DEX save: 4

(Having a -5 dex it autofails)

The mushroom was stabbed and torn by the ice knife, seeming horribly wounded, but still intact. The mushroom didn't shriek however, and didn't even seem to know it had been hit.

Zerxius runs forward and strikes the shrieker with his staff Attack: 7 Damage: 5

then punches it on the follow through Attack: 19 Damage: 6

Seeing Zerxius rush towards the mushroom, Grabius chooses to get Ready to throw a dagger should anyone come out, and bonus Hide in preparation.

Stealth: 14

Boxey is also going to draw her crossbow and load a bolt in case someone comes out the door. 

As soon as Zerxius got within 30 feet of the shrieker it started shrieking. The goblins immediately woke and turned to see the intruders. They loaded their shortbows and prepared for battle!
