Felix has seen glyph like this in the past. This glyph of warding on the door triggers a thunderwave spell if the right requirement is not met.

Felix looks down and tells the others "It's got a glyph on it. It's set with a spell of thunderwave. I'm not good with magic."

[Do I know anyway of disabling it?]

OOC No, the way of disabling is not clear to Felix.

"I could set it off and pray that I can make it in time if you all can't find a way to do something."

Irommek takes a closer look at the glyphs to see if there is a way to disarm it.

OOC: Arcana check as well - 9

...there's a reason Irommek is not a wizard

The glyph looks like fancy graffiti to Irommek.

"I think Oniss may have a good suggestion.  We can try to press the tiles on the door in the same order as the ones we stepped on to get here.  Maybe we can climb down and use Kurma's rock to throw at the first square to see what happens?"

"hummm a thunderwave spell would harm us and probably pushes you back on the chessboard where you'll be engulph by flames.....this place is evil !"
"I guess that the tiles on the door have to be pushed in a certain order as well"

Kurma is intrigued by the Glyph, he meditates a few second (Guidance) and focus is attention on the glyph.
Arcana : 14 + 3

Kurma deduces the same things Felix told them. This glyph of warding on the door triggers a thunderwave spell if the right requirement is not me, and if the trap is triggered there is a chance to fall on the previous ledge and, perhaps, activate the fire trap there.

Is there any space to tie a rope somewhere without disturbing glyph.

OOC No. the door does not even have a handle.

Kurma notices that the higher glyphs are pretty hard to reach and suddenly remember the tale that Inete was talking about.
"The man and the crocodile ! 4 tiles to press, we need 4 hands... Oniss you were maybe right, it might have something to do with the tale"
"What if Oniss stands on the back of Gertrude, then you should be able to press all tiles together"

Then, remembering the flames for the chessboard, Kurma adds "For safety, we probably would need to go back down while you push the door, I guess"

"Right!  Great call."

With that, Irommek climbed back down to give Gertrude and Oniss room to climb up to the door.

"Wow that's the dumbest smartest thing I have heard of... How about I get on Gertrude's back and we press the tiles?"

Oniss walks to Gertrude and waves her to the wall.  He looks to Felix,

"We have this.  I would rather get a look of any treasure that is on the other side of this door before everyone does."

Gertrude nods. She steps up to the door and gives Oniss a buck-up onto her shoulders. Then she again motions for everybody else to move off the ledge and to hide behind. 

"On THREE: Put your hands on the top two glowing tiles. I'll put mine at the same time. If the thunder wave is set off and you're pushed off the ledge, try and land on one of the tiles that are safe. Here we go: ONE, TWO, THREE!"

Kurma is crossing his fingers, getting ready to jump to heal the 2 if they fall onto the chessboard.

"Good luck!"

Irommek uncorks his ale and proposes a toast to their continued health.

Felix shrugges his should "Don't die yeah." and he steps back.

Brunella nods, ready for whatever may happen.
