Fair enough!
The fire on the landing pad is mostly out at this point and it is more or less intact. Just very badly scorched and cratered. The minute you return to it, the turbolaser begins to swivel back toward it to lock on to you.
It will be a Leaping roll to get up onto the dome, and an Agility check to see if you get vaporized or not. From the landing pad, it will be three more checks to see if you get hit.
Getting this started, Rianna takes a running leap up onto the dome without a problem! With her Defense factored in, the turbolaser has a pool of five. A single success is measly, but Rianna rolls none in return so she takes 3 damage as the bolt skims and splinters the edge of the dome.
Moving closer at full sprint, Rianna pitches herself forward into an awkward dive UP the dome when the next blast comes in. They match each other, and so Rianna evades the turbolaser. Instead it tears into the dome just behind her, causing some of her footing to warp as she presses on.
On the final roll, Rianna throws herself into a leap toward the turbolaser, sailing just over the next blast. This one misses and simply takes another chunk out of the dome.
You made it with minimal damage to yourself. You are now in the 'courtyard' at the bottom of the tower, which is lined with air filtering equipment and atmospheric sensors and all sorts of other technical junk. The turbolasers, each the size of a small house, are in the courtyard as well.
The tower is at the center and is a tall gray cylinder. There are only windows at the very top. At the bottom, there are maintenance hatches for access.
