How to Participate:
Flag the event:

To take part in "Crystal War Revisited," talk to any of the moogles found at the following locations:
Southern San d'Oria (K-9) / Northern San d'Oria (D-8)
Bastok Markets (G-8) / Bastok Mines (I-9)
Windurst Woods (K-10) / Windurst Waters (northern F-5)
Participate in the Raids:

Raid one of the beastmen-held positions and obtain a fragment of the Huge Crystal being kept there.
There are six beastman strongholds: three lower-tier ones (Ghelsba, Giddeus, and Palborough) and three upper-tier ones (Davoi, Beadeaux, and Oztroja).
In each stronghold is a Huge Crystal (which looks like a Home Point crystal) with a Notorious Monster that spawns approximately every 50-70 minutes. (The NM will spawn once per Vana'diel day)
You may check the Huge Crystal once to collect shards. If you're in the area when the NM is defeated, then for a brief period of time you will be able to check the crystal a second time for extra shards.
From the lower-tier strongholds, checking the crystal the first time will give you 1 shard. Checking it again after the NM is defeated will give you an additional 3 shards.
From the upper-tier strongholds, checking the crystal the first time will give you 2 shards. Checking it again after the NM is defeated will give you an additional 4 shards.
After collecting shards, you will need to turn them in to one of the Moogles before you can collect more from any of the strongholds.
You can collect and turn in shards more than once per Vana'diel day.
Shards do not show up under Items or Key Items



Regarding the Notorious Monsters
They will spawn claimed by the person who last received shards from that crystal, if they're present.
It is recommended for the person who has claim to Call for Help, so that everyone present can help defeat it faster.
If killed without Call for Help, they will give no EXP upon defeat, as well as no drops. Others around will still be able to get extra crystals.
You do not have to engage the NM to get the extra crystals. Just be nearby when it dies.
You must be within a certain range of the Notorious Monster when it is killed to be able to get the increased amount of crystals.
If you've already collected extra shards after the NM's defeat, then waiting around for additional NMs will NOT allow you to collect more shards. So at most, you may only carry 4 shards (from a lower-tier stronghold) or 6 shards (from an upper-tier stronghold), and will need to turn them in before you can collect anymore shards.
You need to be alive when the NM dies to be able to claim your extra shards.

Turn in the Shards:

Should you safely obtain a crystal fragment, return to town and report back to the Moogle. Work together with as many adventurers as possible to secure victory and earn your nation the title of most powerful among the Allied Forces of Altana!
The Moogle will keep track of how many shards you've turned in and will reward you based on how many you've collected total.
Your Hometown will receive the credit for the collected shards even if you do not turn them into a moogle in your Hometown.
