The assorted group of mercenaries approach the tunnel. Myoko and Frost can fit in quite easily, and even Vardaal, leaning forward can get in. But Torqua and Kavac are a different story. Neither of them can very well get into it, being as round and big as they are. But also, neither will give up so easily.
Frost scouts a few meters ahead, and finds out that the tunnel gets wider, so Torqua uses her magic to "gently" open a bigger hole. Luckily, the tunnel doesn't collapse, and seems pretty solid, due to the moisture of the near water.
The group crawls his way, and after about half an hour of crawling, the hear a def noise. Kavac looks back, and to his horror, he sees no more light from the entrance. Torqua's spell might be taking it's toll on the tunnel perhaps?
The Goliath hurries the others, as he sees the sand collapsing right behind him!
[sblock=Skill challenge]
Roll athletic or endurance as primary skills to save yourselves from the falling sand of the collapsing tunnel!
As before, DC is 15. If you fail more than 3 times, you are trapped in the collapsing tunnel, if you succeed 5 or more times, then you reach a safe area.
You can make all the rolls at once, or one at a time, your call[/sblock]
