Alignment detection dagger
From Ardrana
The alignment detection dagger is a well-made dagger with five small gems set in the hilt. When a command word is spoken and the dagger is pointed casually in the direction of a person or object within 30 feet (the entirety of the dagger’s blade must be exposed), one or more of the jewels glows to indicate the subject’s alignment. The usual codes are:
| Stone | Alignment |
|---|---|
| Emerald | Good |
| Diamond | Neutral |
| Ruby | Evil |
| Topaz | Chaotic |
| Sapphire | Lawful |
Thus, the emerald and sapphire set in an alignment dagger glow if it is pointed at a lawful good character. The alignment dagger is a normal weapon in all other respects.
Note: The alignment detection dagger originally appeared in this form in Dragon Magazine 91 for the AD&D game from TSR. Its use here is for the purposes of providing context for the campaign only.
