If you are going to tame one of these with no dinos, be sure to upgrade your movement speed and get tranqs. When you see it whip its tail forwards move to the right you will dodge the shots. This worked for me.

I built 3x2 stone foundation put stone door ways all around it then I put stairs on one side outside side by side so the dragon can run up

Make it chase you

run up your stairs/ramp

Once it come in run out a door way

Go back on stairs outside n shoot with tranqs

My level 85 took 22 tranqs

Also used same pen to tame X trike n pretty much anything that can’t fit through the door ways

Completely irrelevant but I think it looks kinda cute.

Thorny dragon can act as a turret, set tange to high, fill it up with stone so it cant move and set to aggressive. It is beaver version in desert,doesnt collect berries thoe.

Argent can pick it up now after tlc 2

Be sure and name your first Thorny Dragon "Me So Thorny." Epic.

I tamed my first thorny by simply being on a rock ledge above it, paying close attention if any tail spikes were thrown and dodging easlie. The ledge took most of the hits and I used trank arrows to take it down. I didn't know what it ait so threw in everything. Meat, they like meat. So that's how I got my boy, Chibi.

Super cute, they eat raw meat(I thought they just ate berries and were a passive tame) don’t approach them they will throw their quills on their tails at you(learned that the hard way) they make noises that will make you think your going crazy, but tranq them an then you have a thorny baby

Best at gathering wood and thatch and knocking creatures with a handy Smithy
