From 12:01AM PST (Midnight)/7:00 UTC on Friday, April 21st, 2017 through 11:59PM PST (Midnight)/7:00 UTC on Thursday, April 27th, 2017, all servers will have bonus experience for All Access Members! This will be applied to Adventure, Tradeskill, and AA.
It is our understanding that this does not double Quest or Ascension XP.
Gee, how hard to add bonus status too…sigh.
Bonus status is almost always a separate event.
About Ascension XP, this is not so obvious, normally the last mob of a goblin nightmare gives up 5 keys and 60 000 ascension XP, to day with double bonus it’s returning 84 000 XP so … don’t know the way computing is done but there seems to be an exceptional premium 😉
When they say “double”, they’re referring to base exp.
According to your numbers you already have a 250% XP bonus. Your base ascension XP in this situation would be 24,000, but the 250% bonus increases that to 60,000. The double XP week adds another 100% to the base ONLY, giving you another 24,000 on top of the 60,000, for a total of 84,000. 🙂
