One of those things that doesn't exist, but should?

Everyone's familiar with the Scroll of Deep Descent. You know the feeling...you're just beginning to accumulate your starting equipment, and on dLvl 3 you read an unknown scroll and you're suddenly in a dLvl that's far deeper than your cLvl 2 Mage is able to handle. Or it can be helpful in those cases where you're trying to dive quickly and you've already ID'd the scroll, and it comes in quite handy in expediting your dive.

It occurs to me that there should be a corresponding "Scroll of Steep Ascent". As with Deep Descent, it could be annoying...such as when you're trying to dive quickly and you read an unknown scroll, and you suddenly find yourself rising several levels with your "Max Depth" reset accordingly. Or it could prove helpful for those cases where you've already ID'd it and you want to ascend quickly after deciding that maybe you weren't quite as ready to deal with those Ancient Multi-colored Dragons as you thought you were.

Heh.
Just sell/give all early scrolls to shop 5. There are absolutely no important scrolls on the floor between levels 1-30 that you cannot buy back from the shop.
Unless the treasure feeling was very high or the scroll was a monster drop/chest loot.
