The Templar, Moogle Knight, and Alchemist classes can give units the Astra status. Al-Cid Margrace, as an Agent, can also give a female unit Astra with the Reception ability. Astra can also be granted to units by the Shield of Steel Opportunity Command, which affects the user and the three ally surrounding it.

Astra not only prevents targets from being inflicted with the Doom status, but targets that are already inflicted with Doom can be saved by Astra if Astra is used before the countdown reaches zero.
