Guild Wars 2

is it everything u open?
or rank up rewards?
pvp tracks give u gilded boxes too, so do i get the bonus if i bring in gilded boxes from
pve and open them in here?

do we have any clear guidelines>?

whenever you complete a part of the reward path you will get a chest. Sometime it’s a weapon chest from the dungeon, the other times it’s a loot chest.
Something like “Champion Mouth of Zhaitan Loot Box” from the arah path.
Afaik it affects the loot in these loot boxes.
At least we recognized a certain raise in ascended drops from these boxes during the boost weekend.

what if bring loot boxes from pve into heart of the mist and open them there?

It only affects PvP reward. PvE champion bags are not affected by any kind of magic find.
