Crusader Kings II v1.06b Patch

Paradox Interactive has issued a new patch for Crusader Kings II, adding a separate set of Muslim feudal (Iqta) laws and a separate Muslim invasion CB with longer truce and no taking of all occupied provinces. Also, the success chance for kill plots now increases drastically past 100% Plot Power, and Empires now cost 400 Piety to create (up from 200). A playable demo can be found here.
