Guild Wars 2

I am trying to get Shiverpeak Explorer, Maguuma Explorer, and Hint Completion. I am missing 2 on the two explorer achievements and one for the hint. Any guesses on what it could be or suggestions on what I should try?

Hint completion is easy. Press the ? on your top menu bar. The hint list checks off the ones you have. Just look for the one missing a check.

The explorer ones, I would recommend going to the wiki and loading up map pages from those areas. The wiki lists each ‘zone’ within each map and whats in them for hearts, etc…
Look for zones listed without anything needed for map completion like pois/vistas/hearts in them. Those are the zones most commonly missed since theres nothing guiding the player to them. You can then compare the ‘empty zones’ off the wiki map picture and your own map to see if you have it unfogged.

O thanks. It is the mail one. How much until you mail box is full.

I’m not completely sure. something like 10 to 15..its not a huge number.
Make sure to delete any system mail and just have a friend or guild mates send you empty mails to fill it up.
