I have been playing for some time now but cannot locate any henchmen.
The join button does not appear at any time in the "party" box when i click on any individual
Help
To invite other players or henchman into your group, click on them, then up in your party box you should see their name with a little plus icon next to it. Click on the icon to invite them, which will make henchman automatically join. Henchman are located in every outpost in post-searing as far as I know.
I thought henchmen popped up with CTRL, just like player characters. Also, they tend to be found near the portal out of whatever area you're in, in a nice little line.
You can have henchies after pre-sear, after you pass Yek's bend, party inlarge to 6/6. You can see them by either holding ctrl. At Yek's bend, there are Healer, Fighter, Brawler, Cultist, Mage, Ranger, and Enchanter.
And yes, you can have full group of henchies. They are actually pretty good for quests, not for missions, they arent smart enough ;p
I did a lot of mission content with just me and Henchies in an earlier BWE, but it annoyed me that I couldn't have a full group of Henchies. Rather than 6 members I would only have 5, because there were only 4 Henchies. I leveled to 20 with just me and Henchies.
I liked the feature and I am excited that I can have a one to a few extra Henchies now.
