The Collapsed Room has the following text:
You must attempt a Speed roll of 5+ to avoid falling. If you fail the roll, draw a basement tile and put it in play. You fall there and take 1 die of physical damage.
Is it permitted to voluntarily fail the roll if I want to go to the basement and am willing to sacrifice the 1 die of physical damage?
Also, does the answer differ for forced movement? This came up for Haunt 9: The Dance of Death. In that haunt, players must make a Sanity roll or do the following:
you must move toward the Ballroom by the shortest route through discovered rooms. You may perform other actions normally along the way if you wish.
In our case, the Collapsed Room was in the way of the Ballroom, and we were unsure as to whether we could voluntarily fail that room roll in order to get farther away.
So can I voluntarily fail the roll for the Collapsed Room?
