Reduce the spell level of magic mapping, but also reduce its utility: instead of mapping the entire level at once, you choose a point to center your divination on and a circular or square area, with a radius dependent on your divination skill, gets mapped. After this change, it might be similar enough to clairvoyance to be merged with that spell (the difference with clairvoyance is that it currently always centers on the player; perhaps the new merged spell could instead scale with skill by having a fixed mapping area, but the distance you can target it at increases with skill level.)

This does not change the scroll of magic mapping behavior, which still maps the whole level.

The spell of knock cannot be used to escape from an engulfer (the wand of opening, however, still can). Casting knock into an engulfer produces the message “You knock on the inside of [monster], but nothing seems to happen.”

A potion or spell of searching: it doesn’t give you the regular searching intrinsic, but rather it detects any traps you move adjacent to with a 100% chance (regular searching isn’t guaranteed to find these, and this effect won’t find other things that searching is able to find).

Alternatively, just make it give you temporary intrinsic searching as currently implemented, but make it so that timing-out intrinsic searching (available only from this) is guaranteed to find everything.

Nerf the spell of knock in comparison to the wand of opening: it should be a melee-range spell (or a beam with range 1), and possibly it can’t be used to open containers until you are at least Basic in matter spells.

Hitting a statue with a wand of opening (possibly the knock spell too, but it might be nice to let the wand have a fringe benefit) causes it to drop all its contents without breaking.

Spell of probing, in the divination school, that probes monsters based on skill:

• Unskilled limits it to touch range and gives minimal information on the monster’s status, possibly only showing HP like a stethoscope.
• Basic is still touch range but gives the usual amount of information.
• Skilled shoots a probing beam and gives some additional information.
• Expert allows you to select any space or monster in your line of sight within a radius, and gives the same information as Skilled.

The wand of probing is raised to be on par with the Skilled effects.

Confuse monster scrolls grant more charges than castings of the spell do. This means that the uncursed scroll should grant several charges, and the blessed one even more.

The spell of identify is an unlimited replacement from the scroll that makes them rather useless, so nerf the spell so that it only type-identifies items (beatitude, enchantment, and charges will not be considered). If you want to learn these things, you must use scrolls of identify.

• Alternatively, blessed scrolls of identify could be buffed, for example they always give a full identification of everything in inventory, or they identify several additional object classes that are not yet in your discoveries list.
• Also, the identify spell could scale with skill, so that it identifies beatitude at Skilled and enchantment/charges at Expert.
