Wands should require being wielded before they can be zapped; this way it adds a bit more strategy for the player on when to wield a wand and which one, and balances them a bit relative to monsters. On the other end of the change, you now get a turn or two of warning when a monster is about to zap a wand, because they have to wield it.

Greasing your weapon prevents monsters from disarming it with a bullwhip (though the attempt may cause the grease to wear off it, like usual).

If you are an elf, you can read any object with “runed” in the description (e.g. elven spears, daggers, bows, and the runed wand). Though, elves will know the identities of most of these items by default, so they won’t appear “runed”, which might defeat the purpose.

In any case, the message should be something relatively inane, like “Made in [elvish sounding place]”.

The Oracle offers a service in which she reallocates some skills of your choice, costing some amount of money. Perhaps she can only skill you up to skill levels you formerly had before forgetting them, or else she can only make you forget skills (but you get to choose which unlike with amnesia).
