List of missable content (XCX)

The following is a list of missable content in Xenoblade Chronicles X.

Lao
Due to story reasons, the BLADE Lao is not recruitable after is started. Although there are no achievements related to Lao, all s involving him are made unavailable:
 * Every Dog Has Its Day
 * Training Troubles
 * The Fan Club
 * Teamwork
 * The Winds of Change

Lao's gear can seem permanently lost, but all of it is returned upon completing Doug's fifth and final Heart-to-Heart, Love and Loss.

Missions

 * During the mission City Saviors, the player can choose to kill or spare the Little Suids before they become a threat. Killing them means the mission A Painful Lesson will be unavailable. That being said, sparing them may not be the best idea...

Equipment

 * The Sparkjet Rifle is an Assault Rifle exclusive to the mission What the Skell?!, as it is immediately destroyed when returned.
 * The Unbreakable Sword can be refused during the mission The Unbreakable Sword.

Skell equipment

 * During the mission A Girl's Wings, Cross is given a AS0115 Formula XT, a version of the Formula designed for flight. After it is returned at the end of the mission, all equipment attached to it is lost.
 * All Caladars are mission-exclusive, but many of them have a chance of dropping Skell weapons made by Six Stars. Since many of these weapons only have a small chance of dropping along with their own random Augments as traits, they can be missed:
 * The series, which grants the Skell Art Sunburst
 * The A-Spear series, which grants the Skell Art Astriad Flicker
 * The F-Arrow series, which grants the Skell Art Obliteration Bow

Miiverse
Because the Miiverse was shut down on November 7, 2017, the BLADE Report feature has been disabled. This means that the achievements "The New Reporter" (achieved by filing a BLADE Report) and "You Tell 'Em!" (achieved by recommending another player's BLADE Report) have been unavailable ever since.

Online Shutdown
The online shutdown means that all BLADE Missions and Squad Missions will be unavailable. This also means that Global Nemesis Missions are unavailable, making The Planet's Guardian and The Final Menace drops much rarer.

Reward Tickets
Players will only be able to earn 5000 Reward Tickets over the course of the game by 100% finishing the entire survey of Mira. This means that spending has to be planned carefully.

These s will only drop through online missions.
