14 hours ago, Sturn said:Typically I don't allow a repeated attempt unless there is some obvious change. For example, if the PC fails to use Computers on the door controls to open it up, I'm not going to let him keep rolling until it opens. If he demands to try again, I'm responding with something like, "yeah you realize after your first attempt that it's impossible to trip the hypertensile actuators with the tools you have." But, if he later returns from the speeder with the tools he forgot, then sure I'm allowing another attempt. For the limited occasions that I do allow a repeat for some reason, it's going to be increasingly more difficult (upgrades) for each extra try.
I'm pretty much the same although I will consider a second attempt right away if there was no outright success or failure. Meaning if the success and failures actually cancel themselves out I may give them another chance using the adv/thr to effect the next roll. If they get even one failure, I fall back to the stance you posted.
