My brother was trying to get the First Hati that was related to the Titanstrike artifact. He said he did all the quests for Hati, but He never Got Hati. So is Hati Not acquirable now? if You don’t already have it? He did this on 2 Hunters, and didn’t get Hati on either Hunter. So should he continue and do the New part for Hati, and see if he can get Hati Now?
I believe they should be able to get the new one, and then you can get all the skins independently instead of just the default.
The Hati from Titanstrike is a skin now that you can get after doing the stuff to get him back just go talk to the storm guy on his tower after all is done and he will let you tame that as well as other skins.

You can still obtain Hati it’s just a little bit different now.
Well my brother thinks he picked the Wrong answer when he was doing the final quest. And I don’t actually know what all his choices were, but would that cause him NOT to get Hati? Now when he went to Tiragard Sound to talk to Mimiron, He wasn’t there… So why would they give you a choice Not to Take Hati… Im confused as to what problem my brother is actually having. I have looked and Looked for a Link to the Original questline so I can see what his final choices were, but I cannot find it anywhere.
