True that is,
but you'd have to know your limits, and keep in mind in which dungeon you'd be able to use it, which, to me, is still kind of immersion breaking.
On the other hand, you'd not go jumping in a place that's barely your own height..still.
Dunno.
Did you find the board or look at it in the dummy cell yet? Just asking, because you say 'jumping in a place that's barely your own height'. It does not increase your jump height while it is in inventory or something similar - that would be very problematic since then you would go through the ceiling whenever you jump in a location with a low ceiling. It is only some kind of solid magic energy that can be used as an elevator when you stand on it. To clarify the problem here is a screenshot:

Problem is I found a few locations in exteriors where you can go through the ceiling as well. Like entrances to houses for example. Not very likely that someone will use the board there, but it is the same kind of annoyance. It
can happen. I tried some things to prevent this, but no luck. The only solution I can think of is to cut the height of the magic energy in half. I don't think there are any locations low enough to cause trouble then. But the board will become almost useless if I do. Right now it is 160 units height (Imperial race has a height of 128 units - on the screenshot it is not completely raised yet), then it would only be 80 units. Maybe I'll even use 64 units only to be on the safe side. But it is a nice effect and maybe it is still useful in some cases when only two feet height are missing to reach something. And maybe I find a way to prevent this bug from happening for later versions (if anyone has an idea please tell me).
