Sorry for the necro post, but I have encountered the same issue, I want to play as a Illithid Wizard, and he makes three attacks per round with a Crossbow, the same as the topic author have described;
I tried to deactivate the "natural weapon", by doing as the topic replyer says, but to no avail, it not work, i receive a message saying "Lost Item Illithid Tentacle Medium", but it continues with his 3 attacks, and reselecting the tentacle tag in the PRC menu also not work, it neither unnequip or equip the tentacle anymore, as the menu revert to the previous page and nothing happens, and it continues with his 3 attacks;
I tried edit the bic file with Leto 1.69 PRC, but it corrupts my save/bic file, as I not sure what I have to modify in the Advanced Editor, or how to save the file, in the Advanced Editor;
Could someone please help? I tried google it for some time, but found nothing, only this post describes exactly my problem, and the solutions in it not work for me, so I registered and posted my problem; I'm using the 3.5 version self installer of the PRC, in a fresh NWN Diamond 1.69 installation;
Thanks in advance; I Love the PRC!
