I found out that if you have the Idol of Silvanus in your inventory and transfer it between characters while in sight of the Strange Ox, the entire herd aggros and attacks you. Cue the speculation!
Edit: Did some testing, apparently all the tieflings react the same way, so it's not some scripted event for the ox :(
The strange ox is definitely something, tho I still don't know what (not searching yet to see if I can find out ingame), you can talk to it with the spell speak to animals, the interaction is intriguing.
yep, but it seemed to lead to absolutely nowhere. Left me a bit puzzled.
Kinda leaning on the theory it might be a druid who wants some bovine action, or something equally weird, and thats why they won't speak up on what they are up to.
It's in the stables of the Last Light Inn. The loot if you kill it is the same as if you kill it in act 3 (better loot than if you killed it in act 1). Though if you kill it you miss out on an act 3 quest.
I recommend not killing it, and instead helping it when asked. I don’t know how to do spoiler text but there’s a good reason to help it in act 3 come final fight time
