Xiticix Antennae: The antennae are outlined in detail in the Xiticix Invasion™ book. I will summarize:

Vulnerabilities: All sonic or vibration based attacks inflict an additional die of damage and knock out the abilities for 3D4 melee rounds per blast. White noise negates auditory abilities and halves all other antennae abilities, as well as causing a painful headache.

Auditory Abilities:

• Track by sound alone at 66% +1% per level if the character is a warrior (Headhunter, Special Forces) or hunting (Huntsman-Trapper, Bounty Hunter, perhaps Wilderness Scout) type, 1000 foot range.
• Detect movement and track by motion detection. 50% +2% if the character is a hunter type. Follow and locate prey using motion. 500 foot range.
• Feel the vibrations of approaching things: Humans at 2000 feet, flying vehicle/large animal 4000, ground vehicles/herd of animals up to 6 miles away. Reduce detection of other flying things to 500 feet in strong winds over 25 mph.
• Hear ultrasonic sound at 2500 feet.
• Communicate through ultrasonic sound. Unlike the Xiticix, the sound will be in regular language. The antennae are also capable of "speaking" regularly, as well. 2000 foot range for ultrasonic communication, double if silent.

Tactile Capabilities:

• Identify known objects or substances by touch alone: 65%, 30% if not so well known.
• Identify temperature within 1D6 degrees 75%; includes air temperature.
• Identify wind direction and speed: 85%.
• Detect rapidly approaching objects from behind/to the side within 12 feet: +1 on initiative, +1 to dodge

Olfactory Capabilities:

• Superior sense of smell: Smell odors/scents/chemicals from a mile away and perhaps 2 or 3 miles away if the character is downwind! Two million times better than a regular humans.
• Common/strong scents: Recognize and identify common/general smells or powerful smells: 90% +1%>
• Identify specific/unusual odorrs: 54+2%.
• Track by smell alone: 75% (+2% per level if the character is a hunter or warrior type), roll once every 1000 feet. The character can also sense by smell alone and only suffers half the penalties when blinded.
• Smell large fires and the coming of rain: 60% (+2% per level if a character is a hunter type) with a 2 mile range.
• Recognize "fellow hive members" and Queens: The character can identify Xiticix of particular hives.

Antennae regenerate in 20 days unless the character has enhanced regeneration.

Cost: 8 million, add 500,000 if the character wants to make them retractable/concealable. Subtract 1 million if one brings in the antennae themselves.
