Stairs
From Tardis Wiki, the free Doctor Who reference
During the Shoreditch Incident of 1963, the Seventh Doctor used the stairs to escape the Coal Hill cellar. Making pursuit, an Imperial Dalek elevated up the stairs. (TV: Remembrance of the Daleks)
At GeoComTex in 2012, a Dalek named "Metaltron" seemingly found itself at an impasse when faced with a flight of stairs that Rose Tyler, Adam Mitchell and De Maggio had ascended, with Adam mocking its plight. The Dalek, however, soon began to elevate up the stairs, leaving De Maggio to cover Rose and Adam's escape at the cost of her life. (TV: Dalek)
