Used to have 3 of these; Mallet, Hammer and Sledge. They were killed by a former tribemate because we cuffed him but they got us a full circle of behemoth gates around a lake in 2 days, would recommend for any survivor building stone. Dont hit on the shell only takes a fraction of torpor
Equip your Doedicurus with a saddle, pick it up with an Argentavis and fly near rocks as it automatically harvests the stone as you fly. Level up the melee damage to harvest more stone with each swing. Level up your Argentavis’ weight capacity be an insane stone harvest team.
