It's called HandyNotes. Just remember to install the TimelessIsleChests notes as well. Will show them all on the minimap and map
It's probably faster to just make 3-4 tomtom waypoint macros to load all the coords and run form spot to spot manually......it took me liek half an hour to get all of the TI treasures chest and moss chests and rope chests etc. Sometimes.....its better to freehand than to bot.
Like....why would you compromise your acct buy bottign something thats so simple, on a super small island, with the highest population of characters.....does not compute
Because I, at first, thought the chest system was similar to how the Netherwing Eggs were, with random spawns at different times. It wasn't until a short time after I found out that wasn't the case.
