Zapping a wand of locking or casting wizard lock at a pile of rocks will turn it into a wall, or possibly a boulder if creating walls is too powerful.

Some ways to scale some spell effects with skill. Generally, this consists of nerfing unskilled and basic casting rather than adding even more powerful high-skill effects.

• Beam spells such as knock and wizard lock scale the range of their beam with skill, with only a few squares at Unskilled, up to 4 squares at Basic, up to 6 at Skilled.
• Identify always identifies exactly 1 item when Unskilled.
• Light scales its radius with skill.
• Charm monster only pacifies 1 monster at Unskilled, and can only tame 1 monster at Basic, 3 at Skilled, no cap at Expert.

At Skilled or above, the spell of wizard lock can be targeted at any point (that you can see) in a radius. It doesn’t shoot a beam, and you don’t need to be in line with the thing you want to lock.

Possibly, at Expert, it locks everything within the radius, but this is not good unless you have the ability to choose whether you want this effect to be cast or not.

At high skill, the spell of wizard lock forces items off the doorway to adjacent squares so it can make the door. If there’s a monster on the door, it also gets forced off to an adjacent square, or becomes embedded in the door if none exists.

Using wizard lock on a monster locks their pack, preventing them from using items against you.

Casting wizard lock at Expert skill will transform a door into an iron door or create an iron door.
