Ah, that's the one you were referring to!Pieter,
The option to get Amiel to take out Boon is subject to "if(CalcCharacterSkill(PChar,SKILL_LEADERSHIP) >= 8) // NK". If this a yes then it allows Amiel to do the work for you otherwise it drops you back to earlier dialogue. I didn't realize this until I just had a look at Amiel's dialogue.c file. So most players who go straight there would not have or would never know about this path.
Indeed to get your Leadership to 8 by that point, you need to either cheat or do a LOT of other stuff first!
Maybe it would make sense to reduce that a bit so that players who do a bit of reasonable extra play on the side could make use of it
Otherwise it would be a virtually non-existent option, which is rather pointless.
