Dungeon Raid (Surraruthru, Moore)

[Nephrite]

Moore ponders for a moment as he takes out the mundane iron key he has and flies over with it to wave it experimentally over the diagram.

[Anastasia]

The key dissolves into light and the diagram flares with magic. Something's happening!

[Nephrite]

"Oh." He blinks. "I really didn't think that was... .." He just shrugs and flies back a bit to wait and see what happens.

[Iron Dragoon]

"Well, it fits with what I could glean from the spell circle. As far as I can tell, that was the intended key."

Surraruthru settles in for the ride.

"Here we go. Again." Finnegan adds that part, spear out and at the ready. The platform zips ahead, expanse of lava left behind. Ahead of you are blasted deadlands, save for a yawning chasm into the earth. The platform floats above it and then begins to sink down into it.

[Nephrite]

Moore keeps an eye out for anything strange! ...Well, strange-r.

[Anastasia]

Spot check.

[Nephrite]

Take 10 for 46. I FORGOT AGAIN

[Iron Dragoon]

Curiously peers around at the chasm they're descending into.

[Anastasia]

There's three points of immediate, salient concern that both of you notice.

1. The chasm below is too deep to see the bottom of.

2. Your platform is starting to fall apart.

3. Tendrils of writhing blue flesh are rising up from the chasm and towards your crumbling platform, rather swiftly no less.

[Iron Dragoon]

Rolls to identify the tendrils?

[Anastasia]

K:Dungeoneering.

[Nephrite]

Moore will try with a take 10 for 34

[Iron Dragoon]

> roll 1d20+39+2 K:Dungeoneering

It's not like the normal creepy crawlies that have tentacles. It's either something exceedingly rare, mutated or made by magic. Based on the absurd length of it, it's almost certainly a magical projection rather than part of a creature.
