The Terrible Stair help

The stairs mention that they won't hold two medium creatures next to each other. The problem comes from the fact that my group has a druid with a large animal companion. Is the animal stuck down on the ground or should I fudge it and make the stairs sturdier and less terrible? Suggestions?

Where is the Terrible Stair? What chapter?

Also, you can squeeze into a smaller space. You just lose bonuses when doing so. So I'd say the animal companion can squeeze through.

Its the stairway up the clock tower in the second chapter. And its not a matter of fitting on them, the book mentions that the stairs can't handle the weight.

He's going to have to sit that fight out. Unless you put a Fly or Levitate spell on him ;)

Yeah, I have to agree with Tangent101, like usual, unless the players have some way of reducing the creatures weight, that animal is going to have to guard the bottom of the stairs. If there is a wizard you might be able to have the creature squeeze onto a floating disc, but it really depends what the creature is I guess.

It says that section sways for 1d4+1 rounds before falling.
So, run up, Tiger, run up.

Spider climb would also be an option.

Spider-bear, spider-bear, doing whatever a spider-bear can. Can it climb? Yes it can, watch it go and despair...

Tangent I want that to be a thing now. Anyway, yes, unless he can climb on walls, float, or get smaller somehow, he is stuck. It is probably meant this way, as there have to be disadvantages to large companions, or groups that use enlarge person and permanency on their barbarian.

Like I said, it doesn't fall until 1d4+1 rounds after the section is overloaded.

Two Medium creatures usually equals one Large creature, so that Large companion has at least 2 rounds to move on.

If it said it fell immediately after being overloaded, then he'd be in trouble. But it doesn't.

The party will probably need him, with what waits at the top.
