Hey,
I can't summon Lump to aid me in combat in honour mode. Is that intended or a bug?
It happened to me in 2 runs. First time I promised him that he can feed on the dead, second time I payed him money to get his horn. When I use the horn in combat, I get the animation and the sound, but the ogres don't appear. I also noticed that it doesn't take an action to use the horn, but I can't remember if that always was the case.
I wanted them to aid me against the Gith partol and I know from some earlier runs on tactitian difficulty that it's generally possible to summon them in that fight.
