Fortress Crab
Template:InfoboxRaidBoss Fortress Crab is an event-exclusive Raid Boss which can be fought in Kingdom Hearts Unchained χ / Union χ. Fortress Crab can be encountered if a Raid Boss is triggered while playing the event quest 2016 Showdown! Daily Raid Event on Thursday.
Fortress Crab Ω can be encountered if a Raid Boss is triggered while playing the event quests Raid Level: Legendary! Don't go alone!, Raid Level: Legendary! Don't Go Alone! during August 2016, and Legendary Raid Level: Don't Go Alone! during March, 2017.
Strategy
The Fortress Crab Ω starts at three million HP, however instead of the normal twenty minutes to defeat it, you get two hours.
The top weak point is 
Magic and is the weakest, so destroy that first. The 
Speed point is the next weakest, followed by the 
Power point, however since you'll be using Magic Medals to fight the Raid Boss, these points even out, so go for the one you think you can kill fastest.
Each follow-up attack for this event only costs 1 AP, so it is quite possible to just spam normal attacks over and over to kill the Raid Boss, even with no party members helping you.
You get roughly 3,000 Lux per weak point defeated, but only a small amount for each attack. Therefore it is highly recommended, due to the time given to kill it, to allow the weak points to revive as often as possible, to get the most Lux out of the Raid Boss.
Weekend Raid Event
As of August 6, 2016 there are now weekend only Raid Boss quests that will summon a Fortress Crab Ω. However, unlike the last Raid Boss event, these Fortress Crab Ω's start at ten million HP instead of three. You still only have two hours to kill it, but as long as you have party members helping you and you don't bother to wait for the points to revive, you can kill the Raid Boss within two hours.
You only have to kill three Fortress Crab Ω's in order to get enough Raid Coins to complete the event board, or two if you are the MVP or host for both of them.
Attack Prize Plus is beneficial for maintaining full Special Attack Gauges.
Like in the last event, you still get the most Lux out of waiting for the weak points to revive. However, the crab cannot be killed if the limbs are allowed to revive each time they are defeated, so try to weaken the crab to one million HP before farming it for Lux.
