Petcan will try to cast faerie fire again

DC 16 dex save

Invisible Stalker's DEX vs. fiery teleport: 18

Invisible Stalker's DEX vs. Faerie Fire : 15

The spiders crawling all over the upper half of the invisible creature gave you a general idea of just where it was but it looked strange seeing somethings basic shape outlined here and there by where the spiders were on it and not being able to see it. That changes drastically when it becomes outlined in light, even though you still don't recognize what this creature is supposed to be, it is vaguely humanoid shaped and now also sheds dim light out to 10 feet.

It roars in fury and even that sound is unrecognizable as something a creature would make, it's more a mix of rushing wind and the rumble of distant thunder. It now turns what serves as it's head toward Petcan and Randall and makes 2 slam attacks against them (in order).

Attack: 17 Damage: 10

Attack: 24 Damage: 10

(Randall is up. Pepin is next.)

Randall:

Now in close combat with the being, Randall is unable to keep moving along the wall to keep plugging holes.  Instead, he draws Lightbringer and Swings at the now-outlined creature, commanding his spectral mace to follow suit.

”Keep plugging the holes!” he encourages his allies.

Lightbringer attack with FF advantage:  21

Add bless to that attack roll:  4

Damage (bludgeoning, magic, and radiant):  6

Spiritual Weapon Attack with advantage:  30

Add bless:  3

Damage:  11

Add Spiritual Weapon Crit Damage:  1

Hoping that the others are fine fighting the weird creature, Pepin continues plugin holes to stop the water (although he has his cloak of the manta ray so wouldn't have an issue when the water gets high)

Round 2 Recap:

Zenodor has Irraxan plug another hole while he fires 3 magical bolts at the unseen creature, two of which strike their target.

Tempe throws a ball of fire at it as all his summoned spiders try and bite it again, 3 of them appear to sink their teeth into something but there is no blood to prove it. Pinky teleports taking Zenodor and Tempe a short distance away.

Petcan tries to land faerie fire again and this time meets with success as he lights up the creature ending it's perpetual invisibility.

Invisible Stalker furiously lashes out and tries to slam Petcan and Randall.

Randall uses Lightbringer and his spiritual weapon to score some scathing hits against the glowing creature.

Pepin dutifully plugs another hole to help the group overall, knowing the whole time he's prepared for the worse with his cloak of the manta ray.

8 of 12 holes are plugged. The water level is just below the knees of medium creatures and halfway up the thighs of small creatures.

Finally being able to see the thing, and speculating that this creature is not of flesh and bone, and clearly not of this plane, Z casts Banishment on it. Saving throw CHA DC16 for it to resist being banished (permanently, if not from this plane).

In the meantime, he asks Irraxan to continue to plug holes. 

Invisible Stalker's CHA save: 10

The light stops shining from the creature and it no longer emits dim light out to 10 feet. All the spiders fall to the ground landing prone.

(ooc: if you plan on concentrating for the full minute it will not return and the fight is over, please confirm in a post.)

The chamber is eerily silent except for the water rushing in from the 3 remaining unplugged holes. The water is currently just below waist level.

 (Yes, that is precisely the plan. So it will be banished back to the Plane of Air permanently. There is no need to actually kill it as that's not our mission, and this is a quick way to defeat it.)

Once the creature is banished (and combat is over) Z and Irraxan finish plugging the holes. Z then examines the chamber, the skeletons and any items left there. However, he stops short of the Pedestal with the box and says "I think we should check this carefully for traps before we remove this"

Perception 5

Randall:

”Agreed,” says Randall once the holes are plugged.  He approaches the center of the room but keeps his distance, looking for anything that might be a trap in addition to the guardian and the water they have already experienced.

Perception:  17

Tempe with the help of the spiders try and help finish, plunging the holes

As the others plug the holes Pepin takes a swim in the low water to see if there is anyway to have the water flow from this place.

Investigation: 13

@Randall

The only trap you find is a clever one and you've all already triggered it. The entire floor of this chamber acts as a weighted pressure plate. When a certain weight is reached the floor sinks down about an inch very slowly and thus is not perceived by anyone. The water then begins pumping into the room.

@Pepin

The only way to drain the water is to reset the trap. When everyone leaves the chamber or is not standing on the floor it will rise slowly back into place and reveal 5 drains that will help the water flow out of the room.

@All

The room has an indeterminate number of coins. Depending on how many you want to gather and what you will carry them in I will leave for each of you to describe in a post. Also, you each get to pick a very rare magic item, and after you pick one I will look through the list and pick another for you myself (so in total you will have 2 magic items). This will represent all the treasure you are able to retrieve from this encounter in the time allotted.

Also, feel free to make a few posts interacting with the Battleforce Angel and completing the quest he charged you with.

Finally, everyone advances to level 12.

Petcan doesn't have much that's fancy to load up on loot, so he just does his best to find the most valuable gems and such that he can carry. 

He finds amongst the treasures a most amazing find, a set of bracers. It doesn't take him long to discover these are near legendary Illusionist's Bracers. He touches on their power, able to quickly swing his flaming sword twice. He smiles to himself at the incredible find. 

Randall:

Once he is sure no more traps are threatening, Randall retrieves the coffer required by the Battleforce Angel.  Seeing the vast amount of coins around, he is inspired by how these coins could aid the suffering people of Laurentis and starts gathering the higher value coins, gems, and jewelry, dumping them into his Bag of Holding.

As he is finishing up, Randall finds himself drawn to a corpse reclining in the corner wearing the ecclesiastical robes of Lathander.  Seeing the morning sun blazing from an amulet on his breast, Randall hesitantly reaches out and touches it.  With a warm glow, he is enveloped in the bliss of the blessing of his deity.  Looking down, Randall sees that the much more powerful holy symbol of the priest has switched with his own. Breathing a prayer of thanks, he moves off to the angel and gives him the coffer.

(Bag of Holding can hold 500 lbs and currently has 44 lbs of equipment in it, so significant coinage/gems/jewelry will fit).

(Amulet of the Devout +1 traded out for the very rare version, +3)

Zenodor digs around in the now soaking wet treasure and leftovers and after a while finds a very rare Rod of the Pact Keeper. He is delighted with this find, and wonders what twist of fate arranged for each of them to find such suitable and powerful items. However, he feels a pang of regret that he will not really be able to use all the items he now possesses and will have to store or sell some (ie he can only attune to 3 things).

He then also grabs any easily accessible gold and valuables but does not spend a huge amount of time on this. 

He thanks the Battleforce Angel: "We hope you are satisfied with our part of the bargain being completed - but I fear we are in your debt again for the many useful items we have found here that will aid us in our quest. May we inquire what it is that you were after, and if there is anything further we can do to help you?"

Tempe bows to the battleforce angel "Honored"  then he searches the room with help of the spiders. He avoids the coins collecting only jewels. He finds nothing of magical worth to him, till one of the spiders brings him a book. Looking at the book "Praise be to Bahamut, it is a book written by the great dragon himself." He says a prayer as he begins studying, The Tome of Understanding
