"Prim do you think acid might help?  I can hit the lock with an acid orb."

Orion says, "I can't do anymore Earth Tremors out there.  I don't know how many goblins there are, but we can't stay here for long."

It is a thick, well-made and ornate wooden door with a few metallic highlights and decorations. It has brass handles and a bronze kickplate as well as gold and silver filigree. 

"If a Fire Bolt didn't hurt it, oil probably won't do much better.  Try the acid."

(OOC what are the dimensions of this room?  And do 5E fireballs expand to fill the space like 2E?  I didn't see it in the 5E spell description)

Taxidea shrugs and casts Chromatic Orb (1st Level, Acid Damage) aimed at the lock.  

Attack: 25 Damage: 15

Orion smiles. 

OOC: This octagonal room is approximately forty feet in diameter from wall to wall.

The area around the door handle begins to corrode. Metal bits fall off, including one of the two handles itself. The door opens out towards you a little bit.

Orion approaches the door, and gently nudges it open to see the room beyond.  Perception check 9, plus 3 for Hunter's intuition.

Prim stands about 12 ft from the center of the room, where she can keep an eye on the party and both doors in case she needs to cast.

Orion sees a large room with a throne on a dais at the far wall. Three figures stand at the foot of the dais.

Orion springs into the room, launching himself against the partially open door so that it swings open, and moves to the right side of the room.  

Using his bonus action, he casts Hunters Mark on the largest figure, hold his actions to shoot that creature until the one of the other party members gets into the room.

If I can, instead of holding my action, Orion will take the Dodge action, so attacks against him are at disadvantage.

Prim will move to where she can fire into the other room or at the outer door.

Do the outer goblins seem to be breaking the door? 

If so, does it seem like this round?  She'll be ready with fireball.

If not, she watches the three figures in the other room and casts Ray of Frost at any who seem to be casting a spell

Taxidea follows Orion into the room, moving to the opposite (left) side of the doors preparing to cast Dragon's Breath if they attack.  "Lay down your weapons and give us the orb and you won't have to die in agony."  he says to the figures.  "Or, you know, whatever...I'm good either way."

The larger figure begins to cast a spell and is hit by Prim's Ray of Frost. Roll initiative.

Initiative: 11

Initiative: 5

Prim, what's your initiative?

18 init

7 pt frost dam., both on cha sheet.  "Frosty" is slowed by 10 ft if he moves.
