Thought they would spawn in a just agro the target till the time runs out but still didn't spawn. I did that with 3 supra targets none spawned
after that I did some more farming and got one to spawn randomly so I did more testing
from my testing he has two abilities one is a shield and the other a hyena spawn but he can only use that hyena spawn ones. sometimes he will spawn a hyena that isn't the Cinderthresh Hyena though which is odd.
The why I got him to use his ability's is by agroing him and deagroing repeatedly they will use one of the two ability's never both (from what I can tell)
