Player is walking from point of interest A to point of interest B. The go through a gorge to try and save time. A boulder is in there path stuck between a point where the rock faces narrow. Our intrepid player shoves against the rock but it is too heavy. Not daunted our player finds a rock and a sturdy branch nearby. They then proceed to place the rock near the boulder and wedge one end of the branch under the boulder, resting on the rock. Pushing down on the other end they lift the boulder enough for it to roll free. Any unfortunate people or creatures on the other side of the boulder may get squished.
Congratulations you got much better at *mechanics*!
Congratulations you got slightly better at *trap making*!
