I. What if you will have able start ZC timer only when you have charisma not less then 5 and lvl not less then 18. Nearly you must be in additional 2 players with charisma not less then 2 and lvl not less then 8.
II. For ZC you will get money, fame or reputation something like on this formula : x(constant)*damage that you made*(your charisma/2)*(sum of charisma of all players from your side, including you[who have 1 charisma will count for 0]) / ammount of that players). An axample if you have 5 charisma and you had 3 mates with 1, 2, 2 and 3 charisma, then : x*(450)*(5/2=2,5)*([5+0+2+2+3]/4=3). Total : x * 450 * 2,5 * 3 = x * 3375. If you have one charisma then 1 charisma /2 = 0,5. It will desrease that ammount more then in 2 times (dont forget about [0+0+2+2+3] instead of [5+0+2+2+3]).
Conclusion : more fame , money and reputation for people who have more then 1 charisma; and for you profitable have more friends with at least 2 charisma, that will influence on your money, fame and reputation too.
III. If you have 1 charisma you can be killed by anyone from your faction and he will not lost reputation.
IV. Traders will not speack with characters who have 1 charisma.
V. If you have more then 3 charisma and lvl more then 18 - each score of your charisma will give 2 AC scores to mates around you on some distantion (10 charisma = +20 AC for friends).
VI. If you have less then 3 charisma you will start with less amount of reputation and you should achieve able have private room.
VII. If you have more then 3 charisma you will get access to simple quests for which you will get +50% to repair, throw, FA or any other skills.
