EXP Necklace

Ok so I saw the exp necklace that lats for one day,

i am wondering, does the exp increase the longer u stay on or how does it work? just trying to figure out wut the description is referring to.

So basicaly, if i am on longer than 3 hours, I receive 30% more exp to for each monster killed indefinitely? Until i log off?

Thanks!

You get the 30% extra exp boost until you log off or the medal expires. It expires on a daily basis to force us to get a new medal and re-earn the extra exp. Thus, this prevents over-abuse of a constant 30% exp bump.
