Guild Wars 2

whenever i kill shatterer i do not receive any chests for it

If you’re camping the event on a single character between server resets, diminishing returns stops you from getting the chest. If you’re camping world boss events between multiple characters, make sure they’re at least hopping between two different ones and not completing the same one twice in a row.

Otherwise you’re probably doing it more than once between server resets (when daily achievements reset), so you only get the chest for the first one. The boss chest is limited to one per char per day, the bonus chest is one per account per day.
