correct, you get an ITEM that you can *use* and then you get a little icon that counts down the 1hr or 8hr buff.
but honestly, don't waste money on that stuff.
it's only a 20% boost (that is XP reward x 1.20 )
that means if you take a 1 hour buff you get XP like you played 1 hour and 12 minutes
an 8 hr buff gives you a bonus as if you played 96 minutes longer
but that is if you are constantly earning XP in that time without slowing down.
fly back only once to ESD and clean your inventory for 15 minutes and your Bonus is wasted.
Replay the Azura mission (Stranded in Space) once and get the Azura Personal Com Code. This will allow you to call on the Azura once per hour (in Space time, the count stops when you enter a Ground map). The Azura can relay your Mail, access your Personal Bank and sells Commodities. And since she has a store you can also sell any extra drops you don't want.
And the XP bonuses are most handy in areas where you don't have to fly around a lot. Exploration zones (Delta Volanis, Arucanis Arm, etc.) are ideal for leveling while using an XP bonus. You don't have to travel as far to get to the next mission. Sometimes you don't have to travel at all. Be sure to get the corresponding Exploration mission for the area you are working every three missions to maximize your XP gain.
Not rolled a Klink yet... considering it after I hit VA with my Fed toon. If Klinks level anywhere near as fast as Feds then I still wouldn't bother.
And for the record, I've played maybe 3 PvP matches.
klinks level nowhere near as fast as feds... unless you LOVE repeating nothing but the FE's over and over again, and with the changes to the min levels... you'r gonna be doing a lot of explorers and the FE's, since the klingons dont have that many non FE missions (like 3 missions per rank storywise.)
