(I'm going to assume Doon tied off the other end of line)
Seeing the grapple hook and line Rah gathers the force. He then Combat Pushes away the nearest Osokan, holsters his sabre, takes the line and leaps into the river.
He then pulls himself along the line and climbs out the otherside.
Once he's up he says "Thanks, things were beginning to get hairier than I am! Oh I'm Rah by the way". He then runs to assist Galder and Tanic
Galder sees Doon's plan and feels relieved as he sees Rah making a bid for freedom.
"So far, nothing comes to mind, Tanic," Galder hisses back. "We're waiting for you Master and Ms. Xi!"
He spins around and attacks two injured Osokans on the bridge (preferably the one hit for 18 and the one hit for 11!).
Rah needs a 10 to pull that off. He rolls evens, giving a 13, but then -4 for impairment gives a 9. Eeek! But then, his +2 acrobat bonus gives him an 11. Phew! Rah can make his way across over the next six frames.
Galder using a multiple attack there in the dwindling period of their legality... Galder rolls a +1 for a 16, -3 for impairment is a 13, -2 for attacking two targets is 11. Miss! NOT something you want to try whilst injured, Galder!
Incoming attacks! Bad rolling from the Osokans gives a load of misses, though. Now they all crowd onto the bridge, and soon a ton of attacks will be following.
