Would be somewhat nice if the only method of taming one of these was to hatch it from a fertilized egg (especially if its an end game creature) either looted from the corpse of a wild one or a potential new resource, mantis egg sac could spawn similar to a beaver dam if these have semi fixed habitats. Something beyond the usual bug spray and feed meat/gel/poop or rendering the thing comatose with tranquilizers.
Either way, always thought mantis were cool from a young age so keen to see this thing in game.
