Mechanical Mindflayer Head | New Vehicle for Fifth Edition

The mindflayers of Shum’morak are an inventive lot, aiming their duergar slaves at special projects such as this unique vehicle. The mechanical mindflayer head takes the form of an oversized illithid, tentacles and all. The mindflayer pilots use viewing screens from within that access scrying sensors from around the head itself. The vehicle requires a crew of six illithids to use all of its features. Many of the gears and controls are built specifically for mindflayer control, rendering the vehicle nearly useless to non-illithids.

Equipment and Options. The chief function of the mindflayer head is to patrol illithid lairs and amplify the abilities of the mindflayers within. Special headrests built into the interior allow the mindflayers to use their mindblast power to a greater degree. The front tentacles can capture a Large or smaller creature, allowing its brain extractor to quickly remove the target’s brain. Then, the brain is used as fuel.
