They no longer collect obsidian. I tried it earlier and i only got stone. This is as of the latest patch adding the megatherium

Use Simple Rifle and Tranq Darts instead of arrows to keep from damaging too much. Like for people to see.

they say nothing about how when it balls up its basically impossible to knock out

Use a equus when it’s balled up to tame fast like so people know

Have a mate pick it up with an Argy then as they hover above you you can shoot it in the underside and knock it out much quicker. Bring Regular Kibble or it's a SLOW tame!
