If you want to tame or knock out this thing use a crossbow or a bow but I highly suggest you use crossbow and stay in a higher place you can also you stone walls or pillars to trap it do not use anything that’s less as strong as the stone walls

If you have your menu out while taming, bugs will not spawn to kill you.

Just walk up and passive tame it with prime meat

To breed them without lava enable mating and continuously hit them with wyvern fire Get this to the top I have 6 so far

PICK IT UP WITH A MEGALOSAURUS AND TAME IT FROM THERE IT IS !) TIMES EASIER AS NO CAVE ANIMALS ATTACK IT!!!!!!
