Level 1-5 Easily and even higher : Vanguard Premium Discussions

I found this out and figured out how it works just today. In most of the noob areas there will be a quest where you have to harvest a specific item that is NOT apart of actual harvesting. Each time you harvest this specific item you will gain experience.

At Level 1: roughly 25% exp per a harvest
Level 2: Roughly 20%
Level 3: Roughly 15%
Level 4: Roughly 10%

so on and so forth, except after level 5 where it drops to 2-4% exp per a harvest.

Tested Areas:
Raki - Quest to gather the 'purified stalks'
Gnome - Quest to gather the flame stalk dust(must pour dust onto grates to receive exp)

I know it works on the raki great xp for harvesting
