Treasuer Hunter?

So guys i want to reach rank 1 (wooooot ) in treasure hunter, i need 77 points.
My question is: which chests r "high-end" chests?
Only locked hest?

Chests that require a key worth 600g or more. A "locked chest" counts as you have to use a pick, other examples of the lowest version are Shiverpeak, Kurzick, Luxon, Vabbian, and anything deeper into the games.

This can be an expensive title.

And extremely time consuming. I finally got it after months of doing nothing but chest running in irontoes lair. Fortunately, the higher your title gets the more it starts to pay for itself.

congratz on your new title =) anyways, its a long and kinda booring title to do.
it is very expensive one and takes forever to max

good luck

Also, farming during the Easter event (golden eggs give +1 to treasure hunter when picked up) is also a VERY good way to bring up this title (as it is essentially free).

Sorry for early post

Ok guys, so, then.. What title do u offer for completing?
