The rules clearly state that heroes can jump over pits, and how much movement it costs to do so.
But in some quests, simply stepping on a regular terrain tile may trigger effects too (in this case, Quest #3 in Well of Darkness, where it triggers a rolling boulder, and can trigger this effect multiple times), and it's a safe bet that once the heroes have triggered that once, they're going to want to jump over that tile the next time they need to get past it.
So, is that allowed? Do we simply assume that the "jump over pits" rule also applies to "jump over blank tiles"? Or is there some official ruling about this?
