Just saw the green lava spider running around with no hunters around it, so I thought, let's tame him for the third time (I know hes not unique, just did it for the "challenge")
The tactic I used was pretty simple:
I just stood on the floating rock, shot a few arcane shots, waited till he used Magmatoxin then used deterrence and tamed him.

I also tamed Ankha yesterday, and Jadefang and the blue madexx today.
