Since many of you are asking for clarification,
-The cloak is equippable in the "common item" slot, not the cash item slot.
-The cloak is not tradeable.
-The cloak is unlimited.
-The cloak is only available for level 50-75.
-Regardless of when you purchased Gcoins, if you spend more than 50 gcoins between 01/01 and 01/31 on ANY item in the Lunia cash shop, you qualify.
-Gcoins acquired from a survey DO NOT count.
-The cloak will be issued to you in your cash item inventory, and you can activate the item upon whatever character you choose.
-Gifting does count.
I'm getting A LOT of questions about this, so I want to break it down in a very simple manner, for everybody:
In order to qualify for this, you must
1. Have spent money on Gcoins. It doesn't matter WHEN you bought them, just that you bought them. That means that if you bought the gcoins in december, but spent them now, they still count. That also means that survey gcoins DO NOT count.
2. SPENT MORE THAN 50 gcoins on LUNIA items. Not Gunz. Not Gunbound. Not Soldierfront. LUNIA ITEMS between 01/01/09 and 01/31/09.
