Just started Sightseeing log..

[Avatre]

Thankfully, it was only the ARR ones that were like that. HW and SB only had some that were time dependant(at least one in SB did, can't remember the HW ones if they did or not)

ARR sightseeing logs are time and weather gates also no icon within the world where they are located but getting all of them does give the Apkallu minion

HW and SB have icons and their stipulation the very few that actually have them are timed these also have icons to show where they are while exploring and give exp, final reward are titles though

You are not required to do all ARR to have access to HW and SB sightseeing logs and finishing all of an expansion's sightseeing log will allow you to buy the paintings in Idllyshire
