Use net projectile and on scorched earth instant tame with raw mutton

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

UP IF IT HELPS

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.

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.

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.

Argent can pick it up now after tlc 2

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

If you have a flyer carry one to a taming pen, it's gonna aggro and start throwing spines at everything it sees the minute it lands. Plan accordingly, and use solid walls so it can't shoot through them.

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