I'm late on this but there is still a decent amount of time left.

The Plague Star Event is going on now at Cetus and you can get some pretty decent rewards from it, including the new Hunter Set mods (all players should def get at least Hunter Recovery, Adrenaline & Munitions), new Zaw parts, Arcanes, Snipetron & Ether Daggers as well as even Forma for a limited time only (8 1/2 more days).

Get as much as you can.
