So... completed Void Ark. Last boss Echidna is a fun one. Second add step had some trouble figuring out whether the insta-wipe comes from the order of enemy kill, but I'm pretty sure its an invisible DPS check. Anyway, beat that, got the caster coat (three summoners, no idea how I got so lucky) but now I'm sort of wondering about this farthing.
Now it was the first clear for me, so maybe this is a reward for completing it once a week post clear, but I didn't get a message or anything. To be fair, I haven't checked my inventory since (had to head off to work right after), but I'm supposed to get one of these things once a week from clearing void ark and then turn it into Bertana in Idylshire 5,5 to upgrade an esoteric piece to 210.
But I don't see a quest after the clear, so I'm wondering how you get this Mhachi Farthing.
