# [Fiendish Auger](Rules\Source\bestiary\construct/fiendish-auger-pabtso.md) *Source: Phandelver and Below: The Shattered Obelisk p. 206* A fiendish auger is created when a wicked spirit enters an excavation drill, causing the hulking corkscrew bore to glow brightly with hellfire. Fueled by the fervent aggression of the evil spirit within, fiendish augers can rapidly churn through solid rock. However, those who employ a fiendish auger must keep a keen eye on the machine. Without careful instruction, a fiendish auger indiscriminately bores through creature and earth alike. ```statblock "name": "Fiendish Auger (PaBTSO)" "size": "Huge" "type": "construct" "alignment": "typically Neutral Evil" "ac": !!int "15" "ac_class": "natural armor" "hp": !!int "85" "hit_dice": "9d12 + 27" "modifier": !!int "0" "stats": - !!int "23" - !!int "10" - !!int "17" - !!int "6" - !!int "12" - !!int "5" "speed": "40 ft., burrow 30 ft."
