This tiger’s-eye gem bears a striking resemblance to the eye of a cat, its gaze seeming to dart about.
A revelation crystal help you battle foes who rely on invisibility.
Least: When you damage an invisible creature using a weapon with this augment crystal attached, the creature emits a glowing golden aura for 1 round, allowing everyone to know the square or squares it occupies and where it moves during that duration. The aura is as bright as a torch. Despite the glow in the square, creatures that attack the invisible foe still suffer a 50% miss chance; the glow merely allows them to determine the appropriate square to attack.
Lesser: As the least crystal, but any active invisibility effects on the damaged creature are also suppressed for 1 round (even if the invisibility is natural or extraordinary).
Greater: As the lesser crystal, but it also suppresses active effects on the damaged creature that grant concealment or similar effects (such as blur or displacement) for 1 round. This has no effect on concealment granted by the environment (such as fog or a darkness spell).
Prerequisites: Craft Magic Arms and Armor, true seeing.
Cost to Create: 200 gp, 16 XP, 1 day (least); 500 gp, 40 XP, 1 day (lesser); 2,500 gp, 200 XP, 5 days (greater).
