One use only. The bearer of the Rock of Inevitability can use it at the end of any Movement phase. Place a cursed bulwark (an obstacle that provides hard cover up to 8" long) anywhere within 6" of the bearer. It cannot be placed on top of (or within 1" of) a unit, or placed on a terrain feature other than a hill. At the end of each of your turns, roll a D6. On a score of 1-3 nothing happens. On a score of 4-5 place a further cursed bulwark (this does not require the character to be within 6"). On a score of 6 place a cursed tower (a two story-building up to 6" in diameter).
Cursed terrain features placed in this way must be positioned touching an existing cursed terrain feature, and cannot be placed on top of a unit, or a terrain feature other than a hill or forest. If the terrain feature cannot be placed, or you don’t have the relevant terrain feature, then nothing is placed. Any unit from the Forces of Order within 6" of a cursed tower or cursed bulwark suffers a -2 penalty to their Initiative.
