You don’t need tranqs, it’s a beginner tame

First you need a slingshot with about 30-40 stones

Second you need some narcotics and lots of berries

ALWAYS CLIMB ON A BIG ROCK

and enjoy your triceratops

(If you don’t have a saddle yet that are great bodyguards)

Also a good Idea is to turn your taming speed way up

(I’m a noob and turned it to 100000)

So it took literally 15 seconds to tame

Sorry this is pretty long
