Exult Forum

Is there a mod or a glitch where you can add extra companions? I know it's possible to add an eighth (for a total of nine including the Avatar), but is there a way to add more?

Actually yes.. with a exploit. I never tested this out in Ultima 7 Black Gate though.
Let one of your current party members die. Store them in a chest or some place safe. Until you get the person you want to add, added in the group. If you playing Black Gate, take the're body to a healer or Lord British. In Serpent Isle with the Hourglass of Fate.

NPC's are scripted not to join if 4 NPC's are in a group in Serpent Isle.
NPC's are scripted not to join if 7 NPC's are in a group in Black Gate.

The crash is highly do to clicking the strategy tab. So reframe from clicking it. Of course i never fully tested this exploit out. So good luck.

There is an easier way using the Exult hack tools. You can just select the NPC and set their flag to group. Max you can have in U7:BG is 8 though. I tried to add all 9 party members but it wont let me.
Julie just continues to run around in my game.
