So I have an old Bard/T-Hunter and I realized how much he had in common with my Tamer, and I decided to consolidate the two characters. Instead of just deleting the T-hunter, I stoned Carto and Lockpicking and decided to try a couple maps with my Tamer first. I put LP'n on the Tamer and clicked the first map and realized that I couldn't even look at the previously decoded maps. I got the message that basically said 'Someone else decoded this, you got no clue where to dig'. So I put Carto on the Tamer and sure enough those maps previously decoded by my T-hunter were now diggable. Then I decoded a couple level 3's with the Tamer, and tried viewing them with the T-hunter who now has no Carto and he got the same message. I then took Carto off the Tamer and sure enough those level 3's I decoded with her were still diggable, even though I no longer had Carto. So I guess if you have enough Carto to decode a map, its diggable by you forever, but if someone else decoded the map, you need enough Carto to 'use' that map? I am only trying to clear this up because in the end I don't want to keep Carto on the new Tamer/T-hunter, but I have at least 50 level 5's previously decoded by my old T-hunter. Seems I have to keep Carto on my new Tamer-Hunter until I complete all those maps I decoded with my old T-hunter, then I can proceed to decode as many as I want before I stone Carto off for a more useful skill (Spellweaving most likely). I hope I didn't make this more confusing that it needed to be.
