(Homebrew) Heroes of Bardstown

You approach the door at the top of the map, a narrow door painted with a white symbol of waves - the symbol you saw branded onto the face of the young elven girl you rescued.  The faint voice you had heard behind the door a moment ago has fallen silent.  There is just the sound of sloshing, gurgling water.

"Be on your guards, gentlemen.", the gnome whispers. He stands vigilant as the group prepares to burst into the room.

Rohuzar will open the door 

Guilim moves to stand behind Rohuzar, crouching in order to rush under his companion if the need to attack comes quickly.

Aubrey is ready in the back to follow his leader into another battle, sending Furvus ahead to scout.
Perception: 14 Furvus perception: 12

Rohuzar.  The door is locked.

Aubrey:

 After Rohuzar tries the handle, there is a slam against the other side of the door, and it shudders in its frame.  Water leaks out underneath, and around the sides and top of the door.  Strangely, the water at the top and sides doesn't drip down to the floor, but hangs in defiance of gravity.

INITIATIVE:

• ???:  3
• Rohuzar:  19
• Guilim:  12
• Grugga:  7
• Leelan:  6
• Aubrey:  16

"Look out, somthing's coming." Is all that Aubrey has time to shout (I guess) from the back.

Rohuzar readies his axe to strike at the creature if there's enough creature to strike at. 

Attack: 19 Damage: 5 

Aubrey steps to his left (into the square with the door, opening it if necessary) then peeking out in the corridor again, readying an eldritch blast to be fired as soon as their adversary comes into view.
Eldtritch blast: 23 Force: 8

"Damn! Too late! Fight in the last room?!" Grugga retreats to doorway (1 left of Aubrey) and waits to see if everyone else will fall back. ((Readies the dash action to retreat to the top right corner of the last room. Trigger: if someone else falls back into the last room.))

Leelan barely has a second to think before he the party is assaulted again. He moves back to make way for a retreat (1 block right of Aubrey). As both Rohuzar and Guilim are in the way, he decides to hold his shot for when he can get a clear view of the creature.

(Hold action attack. Trigger is when Leelan has a clear shot of the creature, meaning no one in the way.)

??? check to smash down the door:  5

Guilim will move to attack as well, using his small stature to move to attack then return to his previous spot.

Attack: 13 Damage: Unable to parse dice roll.

The door breaks loose from its hinges and crashes to the floor.  A Water Elemental looms in the ritual pool room beyond!  It squeezes and surges into the hallway, partially occupying the same space as Guilim and Rohuzar.  Two feet of water rise up around them making the space they are in difficult terrain.

All of the prepared attacks go off.  Leelan needs to roll but all of the others hit.  Aubrey, you feel confident your eldritch blast hit the mark.  Rohuzar and Guilim, your blades slash through the watery bulk of the elemental.  There is more resistance than if you had just struck a pool of water, and you think you hit the creature, but you're not sure if your weapons are damaging it normally.

ROUND TWO

• Rohuzar
• Aubrey
• Guilim
• Grugga
• Leelan
• Water Elemental

Rohuzar tries to move further into the room and strike again

Attack: 11 Damage: 7 

"Fall back!" Aubrey shouts, not sure if Rohuzar and Guilim can hear him inside the watery monster.
He places his hex (Hex, dex) on the elemental before unleashing another beam of golden eldritch crackling force towards it.
Eldritch blast: 9 Force: 7 Necrotic: 3
He then moves past Grugga (Two squares west)

Reactionary attack

Attack: 7 Damage: 8

Guilim will move back as well, sliding under Rohuzar to still attack the elemental.

Attack: 13 Damage: 17

As the blade hits, Guilim focuses and the weapon begins to glow with a holy light as he smites the watery being.

Smite: 15

Grugga sees Aubrey falling back to the room with more space to fight and follows (uses held action).

On his following turn, he moves a few feet back towards the door and holds his action to strike the water-monster as it passes through the doorway. ((he should end up far right of the room, middle row.)) He also whistles Zip over to the middle column top row. "Lead it this way!" he calls out to his allies.
