公式如下：100 - 目標君主野望 + (使者勢力信用 / 3) 即為成功機率
實質意義：想勸降？先拿玉璽吧！信用度為 100 的情況之下
成功機率可簡化為「133.33 - 目標君主野望」一目了然
野望 33 以下君主，必定可被勸降成功，83 以下也還有 50% 成功機會
野望 99 君主曹操，也有 34% 機率可被勸降，逆天至極！
三二真是個好遊戲，介面雖然簡單，但卻處處藏玄機，令玩家回味無窮！
附錄原文：
High trust actually makes it easier to get a submission. For example, if you
are Dong Zhuo with 50 trust trying to get Yuan Shu to surrender, your odds
are:
Success % = 100 - 81 + 50/3
= 19 + 16 = 35%
With 100 trust, the success chance rises to 52%.
Interestingly, when selecting an officer to perform the Threat action, the
game by default shows you the officer's charm, which has no effect on the
final result (actually, the performing officer doesn't matter at all except
when it comes to getting caught or captured).
