This plain white quill is valued by those seeking confessions. When the command word is spoken, it will ink itself and transcribe what is spoken. It stops when the speaker lies, resuming when the truth resumes. The speaker becomes aware of the quill's magic and can make a Will save (DC15) to resist. The quill stops working when picked up by another person who must speak the command word to resume it's magic. Ironically witches have the easiest time making them. The quill radiates conjuration, divination and enchantment magics.

This dark green ink is prized by assassins. The ink is venomous if drunk or injected (Fortitude DC 11, 1d2 Con damage, cure 1 save). It's most insidious use is drawing a picture of a snake on a piece of parchment and casting it into flames. This summons a fiendish viper for 3 rounds that will obey the artist to the best of it's ability. There is enough ink for three such drawings to be made.
