It would make a convincing fake, but... you can already tell that there are missing symbols and some are misplaced. It's doubtful this would convince Daela either.

"Yeah looks like a great facsimile, the professor should be happy with that, I'm sure."

Olen hands the fake schema back to Bloody Spear,

"Hey dont let us hold you up. We are going to see if we can get inside, but if not, we will use your example, and make our own fake. Thanks for the look at it."

"No problem friend. Luck to you!" She nods at you guys and walks away.

As for the door, it seems bolted shut. You might be able to brute force it unless you have other ideas...

"I could always do as we did with the last, but I doubt it'll work as well." Vasha seems a little downtrodden by the obstacle, but hopeful someone lets her have some fun.

Kinnik steps up to the door, running his hands over the mechanism at taking a close look.

Provided that he sees no obvious traps, he attempts to pick the lock.

Once Bloody Spear is out of sight, Olen turns to his friends.

"Well it was definitely a fake, so we still have a shot at the real schema."

Looking at his friends studying the door, he asks.

"Any idea how we get it open?"

Olen takes a look at the door himself, to see if he can add any insights.

(I again wish to lodge a formal complaint about the obviously hexed rolls my character has suffered in this campaign)

The door has no locks. The door is bolted shut. There is an inscription that suggests it was bolted shut almost 1000 years ago. 

To open this door will require brute force.

(Or something more creative if you guys have ideas.)

(sorry copy and paste on phone not helping. Door suggests it was made out of bounds by King Galifar I in the year 32 yk. It's 998 to now, I believe.)

"Friends, I don't think this is a door, I think it may be a seal over the door."

Olen follows the line of the bolts around the door.

"I don't think we are going to get through this one with finesse."

Olen turns to Vasha

"Maybe your talents are worth a try Vasha. I would suggest a very powerful blast to the centre, or maybe more precision focused here along the seam around the edge."

Olen waves at the others back to give Vasha room to work, stepping back 15-20ft himself, so as not to get caught in any backlash.

Cap backs off, letting Vasha do... whatever she plans on doing.

Kinnik leans forward, blue eyes flashing with expectation.

(No pressure)

(What does Vasha do? :o )

Onecece everyone was good and clear of the door, Vasha steps forward once again and begins to tumble her lucky coin. The arcane power in her veins swelled and rushed through every fiber of her body as though the coin was forcibly drawing it all out. At last, once coin glowed bright-white, Vasha threw it forth. A trio of arcane missiles erupted from the focus and slammed into the barrier ahead, causing old dust and debris to fill the air.

Once the smoke had cleared, Vasha looked on at her handiwork, but the door stood . "I THOUGHT THAT WOULD WORK?!?!?!" Her hands quickly clasped over her mouth and a moment passed before she released them, "ANYONE WANT TO-" again he covered her mouth. Another few moments passed before she dared again, "TRY HITTING IT!!!" She didn't cover her mouth this time, but was obviously annoyed. "THIS IS ANNOYING!!!" She yelled.

Open steps up next to Vasha,

"It's all right, you don't need to say anything, maybe just nod or shake your head. Is the shouting another side effect?"

Olen examines the door, while he gets his Crowbar out of his pack.

Kinnik arches an eyebrow at shroud's use of the offensively-named item.

Olen looks at Kinnik and follows his gaze down to his crowbar,

"What? You know the name fits, I mean, who better to get into a place, right? Think of it as recognition of your kinds natural giftedness"

Olen gives Kinnik a wink, before turning back to the door.

Mollified, Kinnik slowly walks around the room looking for evidence of anything else that may help.

Perception: 19

 Vasha nods to Olen before blurting out, "IT HAPPENS SOMETIMES!! MAKES IT HARD TO GET AWAY FROM GUARDS!!!"

The door is successfully pried open as Vasha's MM managed to loosen the bolts enough for Shroud to do his dirty work. The first thing you all notice, peering within, is that the walls and floor are covered in a thick layer of dust. It's dark inside and those without dark vision (which is all or most of you) need a torch to see. From what you can tell, this door leads into a long hallway.
