[3.0] The following adjustments have been made to the Void Ark:
The weekly restrictions on rewards obtained from coffers has been abolished.
Weekly restrictions on mhachi farthings have been abolished.
The Echidna Card which dropped from boss enemies will now drop from treasure chests.
Mhachi Matter has been added to the item rewards received upon completing the Void Ark and can be obtained once a week.
By speaking with Smacklix in Idyllshire (X:7.6 Y:4.8), players can trade their Mhachi Matter for any Materia of their choice.

[3.0] Players at level 50 and above can now gain experience from all of the bosses in the following dungeons:
The Labyrinth of the Ancients / Syrcus Tower / The World of Darkness
Seriously, why not do the same thing for ST, CT & WoD? Make it so the quest The Gift of the Archmagus Also has Mhachi Matter as a reward so the old raids are viable.
