Check their weapons, closely, it shows their kills.
I would do that... but I forgot to mention my adventurer didn't survive the human ambush.
I wasn't expecting to be ambushed by humans so close to the fort. A couple of my party members got away because I died though.
I was checking their Legends screen entries. There were only 7 of us and 7 of us appear as becoming heroes to our civ. Though that info is kind of hard to look up, but I wrote down our names and checked each one. And not one of us is given the credit of killing the troll. I tried looking for a troll in Historical Figures that died in the year I was playing, but that in mostly scrolling through a endless list and couldn't find him. In the end, I was thinking maybe you need to report significant kills like that to be given credit or maybe the troll played possum. Or possibly I had a single party member who wasn't marked as a hero of our civ and that person finished it off. Either way I kind of wish there were other ways sorting info in the Legends mode. In entities, being able to search by birth year, death year, and race would be nice. If I could limit the list to trolls I could have an easier time. I also wish that party members would appear as related persons in your character's entry or possibly give character parties an entry under entities. Because there was no way to tell if someone was a party member or not.
Not complaining though, I love it. But I figure if no one mentions these things no one will know. I had a lot fun and a lot of 'fun' playing last night. I got a good laugh too. It was almost a whole new experience considering how adventurer mode was previously. I was raving to friend how awesome the new features were. I sent my friend a long in-character email of my character's life and death. Now off to adventure some more!
