Steps on how to tame a parasaur:

1.If it’s low level you can use 1-5 tranqs but if it’s higher bolas better.

2.you can use fists or a bat.

3. They eat berries.

4. To keep it unconscious just use narco berries or narcotic if you want!

You can unlock tranq arrows at level 21! So it’s probably easier to use bola and fists if you just started. -Boycicle
