Guild Wars 2

does it boost event xp or just xp from kills? do I benefit from it in the new HoT content? also does XP boost help at all for event xp? and does the XP infusion from the laurel vender does it boost event xp? thanks

The mouse-over description will tell you what type of experience it will boost.

Have a look at the wiki… for most game mechanic questions it has a lot of good info that is more detailed than what people can write in a post
