Guild Wars 2

I started FoTM just recently, (I’m at lvl.4) and I heard that playing levels lower than yours gives karma. Wanting to get my legendary, I was wondering how much karma FoTM gives you.

Thank you!

my guildies have said they get anywhere form 8k-10k karma when they do a fractal level 10 below their personal reward level.
You get karma when you finish the last fractal (Deep ocean is included, so the fastest karma would be to do odd numbers)
