Hearing Felicity say the obelisk could be a sundial, Imras heads in her direction to help search, avoiding other ruins on his way there after his unfortunate experience with the cold from the first one.  Spotting her near a statue when he gets close, he moves over to inspect it, moving closer to see if it has it's own weather effect like the others.  He moves just close enough feel any effects, then backs away again.

Imras you inch closer to the statue, testing to see if it too has its own localized weather. When you get into the range in which you think you should be able to feel it. You feel no change from the proximity, it seems this statue is without its own Localized weather.

Not feeling nay weather from the statue, Imras stays where he is for a moment, inspecting the statue and the area around it for any signs of traps.  If he doesn't see any, he approaches for a closer look.

Investigation: 17 

Atticus will head to the obelisk. With the scratches in the floor, can I determine what "time" the shadow of the obelisk is showing? 

"Felicity, I assume if we can tell what time this obelisk shows, it may have to do something with the Imras found, the symbols located on the ruined archway. According to the riddle, my assumption is an hour past whatever time the obelisk shows may be the key to which symbol on the ruins need interacted with." 

Atticus will repeat the rhyme to the others again. 

“An Hour pass the time, The Key is in the rhyme. Voice of melody and tune is how one escapes this room, The time lies in ruin, Break through the stone, Find the hidden tune and let the melody flow."  

Imras you inch closer and closer to the statue, getting within 2 feet before you catch sight of a series of holes along the base of the statue. Making sure not to touch anything you peer down to get a look and see a single bolt within the statue that looks like it awaiting a trigger to fire out. Assuming the trigger is near the base you eventually find a single stone slab that is raised slightly higher then the others around it.

Atticus, you easily find the shadow of the Obelisk and follow it to where the IX scratches on the floor are. Taking the Riddle you look to where the X should be but instead find a busted and cracked stone slab, the X is barely visible on it.

Is the X I'm looking at on the floor or the archway? 

Its embedded into a stone slab on the floor.

Im going to push on it with my staff. If it doesn't move, then I'm going to try to give it a quick strike downwards. 

If that doesn't work, can I tell if this is a removable piece? 

Atticus you push on it but it dosent seem to budge, your strike it with the end of your staff. It gives a little but falls back into place. It is able to be moved but It is made of solid stone, so it is quite heavy.

Atticus will yell to the others, "seems we need to remove this stone from the floor. Anyone with a crowbar? Or someone with much strength to move stone?"

 "I've got a crowbar," Imras calls back, still pondering the trap on the statue.  Noticing the raised stone slab and assuming it's the trigger, he looks it over, trying to determine if he can disarm it.  As an alternative, he looks around for debris or stones that are large enough to be placed in front of the holes to block the bolt when it is triggered.

I'd say let’s get this block out first and go from there. The trap may “strike a chord” somewhere else. Could be worth tripping it if we can discern where it may strike.  

Imras you quickly figure that with enough time you can disarm this trap, the slab looks like it is not only thinner then the others embedded into the floor but it is also made of a different kind of stone that seems to be lighter. Make a Theives tools check to try to disarm it. ((Proficiency + Dex on a d20 right? Or is it sleight of hand? Im not really sure I have never played a rogue.))

With the crowbar, You could attempt to lift the heavy stone slab Atticus is gesturing towards. One person would make a Strength check to attempt to lift it out of the ground.

If Imras starts fiddling with what appears to be a trap, Felicity will back away. She has no idea how skilled he may or may not be and doesn't want to get caught up in any mishap.

Imras pulls out his thieves tools to try to disarm the trap.  Seeing Felicity start to back away, he takes his crowbar out of his pack and tosses it to her.  "Take this over to Atticus, see if you guys can get that slab up."  Then he turns his attention back to the trap and gets to work.

Disarm roll: 11

"Good sir!," Atticus motions to the half-orc man. "You may be able to assist us on such a problem over here. This slab here needs lifted free from the floor." 

Confused by everything that is going on Hawk seeks out one of the strangers he saw in the distance. Hawk choses a random blob and moves toward it. As he gets closer he attempts to tell who it is. 
Perception Roll 7

OCC: Dang NabiitT! I need to add bad eyesight to Hawk's trait list

Hawk you may need some glasses as all of the blobs look the same to you, you cannot discern anyone apart.

Atticus will cast light on the tip of his staff and wave it in front of Hawk. "Over here, my dear boy. Your strength may be of help to remove the stone from the floor here." I will pass the crowbar over to Hawk. 

Hawk make a Strength check at advantage because of Atticus' aid.
