In Extinction they can be found in the Crater Forest at the base of the fallen tower. The webish root-like structures nearby (part of their path) are PERFECT terrain tame spots just above their reach. Perch your argy. Use darts and crossbow bolts. (All bolts will kill these fragile Hellspawn Quails. ). They leave and return so don’t think they are torpor running too soon. Once knocked out feed them berries, keep some narco berries in em for when they are at half way, when they are, force feed a whole stack of the narcos, that’s all they need even at Max level. ( usually) Wait for the tame message. You’ve just tamed the devil. Up to spread the news!
