OOC:
Scared of bridges? Kyros has a mysterious past.
The party begins the trip in the following order: Nalu/Valrakas, Qiora, Rhograx/Kyros. It takes a bit of time for everyone's pace to even out, as there's a pretty big height difference between everyone. The first section of bridges are so sturdy that you sometimes forget that there's a rushing tide of sand beneath your feet.
However, the party encounters it's first road block. A steep staircase that rides up one of the black spires, and at the top is a narrow ledge that one must sidle around to reach the other side. Nalu and Peat and natural flying and climbing ability, but everyone else must make an acrobatics check. Climbing is also possible, but it'll be more difficult.
OOC:
DC 15 for the balance check, DC 20 for climbing the sharp rocks. It is possible to help each other, but someone has to make it across first.
It is possible to do things that will lower the DC, but I won't tell you my ideas because that would be cheating! :P
Edit: If I didn't make it clear, you can do one OR the other. No need to roll both.
