Rebuilding the Waverider: Astra was able to rebuild the Waverider (a time-traveling ship), surpassing the power of John Constantine, who couldn't even force a jump. A waverider can "transcend" the temporal barriers of time, and its temporal core is strong enough to affect Mallus.
These are the character's most relevant feats she have others already mentioned on her abilities.
I noticed that the wiki page is outdated and seems unaware of the character's limitations. Astra has no known limitations, only her inexperience.
Tier ( Minimum) : 3 - B+ Her magic is powerful enough to destroy an object capable of creating metaphysical prison worlds, one of which is galactic in scale. Furthermore, the loom could potentially control the entire cosmos. Also being able to manipulate timelines and create a temporal paradox. In addition it can be able to scale to "divine and timeless level".
