I don't remember it ever coming up. Occasionally I'll ask for it if jumping.You don’t allow a skill check to climb or swim faster?
But there's a limit, this is a bonus of 25% to what they should be able to climb. It's actually probably more if they need to get to the opening and then continue into the room to do anything worthwhile.
As I stated, an extra 5-10 feet ... okay. They leap up from the ground and don't really start climbing for the first 10 feet sure.
But it's just what I would rule.
