The scroll of gold detection, if read when confused (and cursed, possibly), detects silver items instead of gold pieces.

It’s probably desirable to keep the existing effect of trap detection in some form, so it’s a bit tricky to decide exactly which combinations of cursed and confused should keep that and which should detect silver.

The blessed scroll of gold detection also detects gems, and possibly type-identifies any pieces of worthless glass on the level as well (more to prevent interface annoyance than anything else). Maybe rename it to “scroll of treasure detection”.
