An eyepatched badger AI who analyzes Carl's weapon concept and teaches an improved sticky-bomb module.
The Sapper's Table trainer appears as a badger with an eyepatch and hook hand. Unlike Carl's normal scripted instructor, he scans Carl's knowledge, converses freely, and recognizes that Carl already understands advanced trapping.
He says Carl's larger idea is a weapon rather than a bomb and needs persistent minions from a hypnotist's bench, necromancer's altar, spider nursery, or equivalent. He then routes Carl through bomber and alchemy instruction for a two-hour sticky-bomb improvement module.
A rough-talking badger creature with an eyepatch and a hook replacing one hand.
