Alchemical Tool

Price: 10 gp

Construction: Craft (alchemy) DC 20

Description

Invisible ink is a staple of spies, rebels, and secret societies everywhere. Messages written with Invisible ink only become visible under specific circumstances. Revealing the secret message with the proper triggering agent is a Full-Round Action per page of text. A successful Craft (alchemy) check reveals the message without the proper trigger and takes 1 hour (the DC varies by ink quality).

Average: This ink is keyed to either two common triggers or one uncommon trigger, such as blood or acid (DC 25 to reveal without the trigger).
