I ran this again, This mission does not lock till after chest is open. it also would not allow a 111 toon to zone into the instance at all, but it did allow for a TA. even though the TA was accepted, no achievements were granted, and not exp was granted either. was a WASTE of a TA
dropped:
Yisaki's cape of mode
frozen piece of the moon
faded blizzard hands
larada's bestial club
