 **Astroforecast** is  Zi Xiao's Secondary Skill. Using it summons multiple cards that ready themselves near Zi Xiao, and will automatically home in on enemies that get within 7 meters of him, or the target he is aiming at. These cards however do not penetrate the terrain and may hit short walls.

Additionally, each use of Astroforecast will create an Astroaspect randomly, for use in the Astrohouse that  Falling Star and certain ascensions make use of. The chance of different quality Astroaspects changes based on the quality of Occult Scrolls currently held, with higher chance for a certain quality based on number of scrolls of the same quality held.

Despite looking like projectiles that would be blocked by physical shields, cards can still hit enemies through them.

## Card Holding Capacity

Up to 10 cards can be held out at once, with  Under Control further increasing this capacity. Any cards that exceed this capacity are destroyed.

Reserve cards (shown as a number below the secondary skill icon, if any exist) will quickly replace cards after they're used. Reserve cards can stack up to 999, but will be removed after 30 seconds of not gaining more cards.

Reserve cards can be obtained from the following:

* Under Control level 3 will move cards that exceed the card holding capacity into reserve cards.
* Card Printer grants reserve cards when summoning a certain amount of cards. Level 2 and 3 grant a chance that cards which miss will be added to reserve cards.
