Maeguana is the new creature added to ARK Survival Ascended with the Astraeos DLC. It is a nursing creature that will help nurture baby creatures and its skin membrane will be your safety net. However, to do that, Maeguana needs to be tamed and here is how you can do it.
ARK Survival Ascended: Maeguana Taming Guide In Astraeos
In order to tame Maeguana, you need to simply follow the traditional knockout tame method. Use tranquilizers to knockout the creature or a net gun to immobilize it.
Feed the basic kibble, berries, or meat to progress the taming bar and keep repeating the knocking and feeding process until the taming bar is full.
You can also spawn Maeguana by using the spawn command 'cheat gmsummon "Maelizard_Character_BP_C" [enter creature level]' or summon "Maelizard_Character_BP_C".
