Guild Wars 2

recently an amount of experience was added to the end boss chests in all fractals. since then i’ve had a few simple questions that i can’t seem to find an official answer to:

1) do all fractal boss chests give the same exp?
2) would a 99 Molten Boss give the same exp as a 10 Molten Boss?
3) does someone with Personal Reward level 100 get more exp than someone who’s PR is 50? if yes, is the experience doubled?
4) is the boss chest exp effected by Diminishing Returns?

edit: formatting

Different fractals have different levels of exp.
A 21 swamp will probably give less than a <21 molten facility.
99 would give more than 10, but it may not be much more. (havent done 99, but a level 40 molten boss gives less than a level 20something cliffside)

Dont know about personal fractal level, but i doubt it has any effect at all

Not sure if there is DR, but i doubt it.

Is the loot from the ground chest any better in say cliff side compared to swamp?
We generally haven’t had the inclination to try and find out ourselves.

Quick overview: inside the chest at the end is an item called Writ of Tyrian Mastery that gets consumed upon pickup for about 28k xp. Different fractals will give a different number of these, ranging anywhere from 1-2 (28-56k xp) for the very quick fractals such as swamp or molten duo, up to, as far as I’ve seen, 18 (around 500k xp) from Mai Trin boss fractal. So therefore:

1) Different fractals give different amounts of XP, with the longer/harder ones giving out more.
2) From what I’ve seen, the total scale doesn’t affect the amount you get, only whichever fractal zone does.
3) Personal reward doesn’t make a difference either.
4) No diminishing returns, the amount you get doesn’t change if you’ve done the fractal once or ten times that day.
