BioWare have a small present for us today. Instead of a 205% XP bonus, the SWTOR devs decided to up the CXP bonus to 350% until patch 5.1.2.
Update to the 250% CXP Event. | 02.07.2017, 10:09 AM
The math savvy among you are going to notice the current CXP boost in the game for the event is operating at 350% instead of 250% as we originally stated. Since the Mission buffs are coming in 5.1.2 we decided to make the boost even larger until then! Since this was a last minute change, the in-game tooltip will still state 250% but the bonus is in fact 350%. Note that XP and Requisition are still 250%.
Get in there and enjoy your crazy CXP bonus.
