You would actually be up against the same problem, just less floors! Think for a moment, though; jumping between levels is an easy task for a Jedi like Wentar, whereas Farl can't do it. How could he come with you still?
The next set of laser walls shuts off, and the next, and the next, leaving you with seven floors before you suddenly find that the passcode fails to work.
"They've done it!" Farl snivels. "They've hacked the security system!"
Not particularly. The doors leading out of the stairwell have more or less vanished into the wall as Triskatani liquid covers over them. You cannot distinguish where they were. Which leaves you with open stairs.
I think you are complicating things a bit. If it is possible for you to make it down in a fashion that I mentioned, you should find a way for Farl to come with you.
To speed things along, I will make all the rolls necessary to get down. You need two successes to land safely and comfortable, but you take five falling damage per success missed. Leaping reduces falling damage by half, of course, so that is not too staggering.
Here we go:
Second jump- three successes! You spring down with no problem.
Third jump- another three! Again, no problem.
Fourth jump- Just one success this time. You take 2 damage.
Fifth jump- One again. 2 more damage, but you're close!
Sixth jump- Two success, a comfortable landing.
Seventh jump- On the last jump, you nearly hit a laser wall and take 5 damage due to no successes being rolled. Farl yelps, then opens his eyes to see that you are standing about where the doorway should be.
"We're there, then?" Farl says. "I never want to do that again."
