Food Buff – You will get a 3% XP bonus from eating food which isn’t much but you will also get stat bonuses and every bit helps.If you see a little moon symbol on your XP bar, you are earning rested XP, and the blue part of your XP bar is your accumulated XP. Rested XP – Always remember to log out in a sanctuary to get the Rested 50% XP bonus which charges up to 1,5 levels.Preferred Server Bonus – New players who want to level quickly should pick the Preferred Servers when starting out to get the “Road to 70” buff which will double XP until level 70 for 90 days.I do not recommend this for your first class though. You can buy the Tales of Adventure / One Hero’s Journey in the FFXIV store to become level 70 in your chosen class.
