Some guy using all 16 slots to get wyrm ashes right now. Made a billion gil just for logging in and entering a dragon battle. (it would be me, but i'm to lazy to even do that much)
That seems like a real pain. Even with 16 characters, they have to be pretty far along to get Reisinjima access so that's only maybe 2 wyrms per rl hour so 2 hours to get 80 points and 16 characters = not enough hours in the day.
However, I do understand that several people have been working on Reisin access on their mules to abuse (not really abuse, but just get more chances with) the dark matter campaign since the gear that augments can now be sent via same POL account.
