So I wanted to get that sweet trident for that character up there. Unfortunately Slasul hostiled himself on me after our conservation when I sided him and became allies. He hit me and took 20 damage back. I left and killed his enemy and then took the prodigy hoping that would be worth more to him than that 20 damage but nope. Now my character is out a complete prodigy point which basically ruins A LOT of the fun of the game for me.

It probably ought to make him friendly if you have the Prodigy, though I'm not sure how you'd go about it.

Regardless, there is a very specific achievement for killing him if you have that Prodigy(Something that's impossible if you take the Trident), so you can at least get that.

Something similar happened to me as well; after siding with him Slasul would keep walking toward me as though hostile, and then would initiate a conversation on his own.
