The easiest way to tame one:

1. Find wyvern with an egg

2. Put all of your valuable stuff in a crate

3. Get all of the wyvern to chase you

4. Run into lava so they burn or into water bc they can't rlly swim

5. Respawn

7. Steal the egg and raise it as your own

NOW YOU HAVE YOUR VERY OWN WYVERN!!!!!!!
