Do 2x exp cards work together?

So like if you had two it would make 4x?
I doubt it, but just asking for future reference

Nope, but you can use a 2x EXP Card during a 2x EXP event for 4x EXP.

Oh hey I could get 4x IF NEXON DIDN'T FORGET.

Thanks for the clarification

Nope.

Correct.

2x cards do not stack. They do with 2x events, though. That's why alot of people wanted to 4x during those 6 hours of 2x exp, but Nexon rickroll'd us! (:
