Threat Evaluator

This is the schtick by the same name from Feng Shui, p 146.

This is a wet, insect-like compound eye encased in a ring of ARB material. It can be implanted in your forehead or in any large muscle on your body. When activated, make an Arcanowave Device check with the number of targets you are scanning as the Difficulty. If you succeed in the check, the GM gives you the current Body and Wound Point total of each scanned target. You also identify named and unnamed characters. There must be a clear line of sight between the Threat Evaluator and the targets; it's no good keeping it hidden under your clothing, for example.

A Threat Evaluator also allows you to use your Arcanowave Device rating instead of your Perception rating when making visual Perception checks.

The eye has been involuntary donated by a flesh-eating demon. If you suffer a fumble when using the Threat Evaluator, you note only the Wound Point total of the most wounded target, but must immediately attack that target. Unless somehow restrained, you will attempt to devour the target raw, as your natural instincts are overridden by those of the demon whose eye you now use as a cybernetic enhancement. This madness lasts one Sequence per point of positive or negative Action Result.
