The easiest way me and my friend have found to knock these guys out are by just using pteranodons!

How to do it: You use a pteranodon take the aggro and fly up just enough that it can’t hit the pt then you get if the pt run a decent ways away set up a foundation and the cannon, line up the cannon make sure to hit its head it will have a special animation when it takes torpor then when you have the right angle just keep shooting it till it’s out.

Tame food: They take exceptional kibble and eat stone when tamed

Ps: They take massive fall damage and this works for lava golem!

Have fun fellow survivors
