What is a kairuku used for? kairuku battling strategies in ARK: Survival Ascended & Evolved.
Perhaps i belong on a war crimes list for this, but i have a male and female of these with breeding enabled in a building with a dimetrodon set to aggressive, the dimetrodon hatches the eggs with enough melee stat and then eats the hatched babies for an infinite polymer farm
Their sole purpose is to be killed for organic polymer, but you can tame and breed them for it:
Tame a whole bunch of them (you only need one male), and a dimetrodon and pelagornis.
Level the dimetrodon's melee damage a whole bunch and put it in a cage surrounded by penguins set to mating. Put the pelagornis in with them at set it to aggressive, the dimetrodon will incubate the penguin eggs and the pelagornis will immediately kill them when they hatch, free organic polymer factory.
Throw a few females and a male into a small pen. Enable mating on all of them. Hatch as many females (and a couple more males) as you’d like. Bring a dimetrodon into the pen to help with incubating the eggs. Set him on aggressive, and he will automatically kill the babies and harvest the organic polymer (which can be used as a substitute for regular polymer, saving obsidian and cementing paste).
It seems like they also lay normal eggs pretty often, so I like to keep an oviraptor on wander (weighed down with rocks) nearby to boost unfertilized egg laying for basic kibble.
