Recenly discovered, that npcs reaction not only depends on charisma & reputation, but also on random 2d10 modifier. Some manuals say it's 2d6 or 1d10. It's really big randomness, because CHA 18 have only +5 modifier and Hero reputation gives only +4!
Total score 7 & lower gives hostile reaction... What it really means? I've never been attacked for low charisma. 8-14 means neutral reaction, 15 and more gives You friendly reaction (more qusts, gold, npc join etc)
Example: With neutral reputation (no modifiers) and ugly CHA 6 you get 2d10-4 (modifier from CHA 6) so result up to 16 gives You 11% chance to get Friendly (maximum, best possible) reaction, this is really srange. With high reputation You can push charima even lower and still get friendly reaction.
What i want to know is how Really differs hostile-neutral-friendly reaction and is this random modifier 2d10? If yes, how to make it lower, is there any patch for it? Also manual say that some NPCs have own reaction modifiers, but it's not listed anywhere in *.chr file according to DLTCEP, is it really exist?
