With gear, she effectively has a 45 round mag, although shots after her "normal" ammo capacity decrease her acc while upping her FP. This may be good or bad depending on what you're shooting, but she's perfect for low or 0 def enemies that you normally throw MGs at. If you can't figure a use for this, you're retarded.

A quirk though is if she moves after beginning to go into her reserve ammo, her gun will be considered "empty" and she will need to reload.
