Tips and Details

• Due to the dynamic pathing of each of the sparrows, the hit count massively varies between casts, even from the same spot or if summoned directly on top of an enemy so the sparrows start hitting as soon as they possibly can.
  • On average, regardless of where it is summoned, the sparrows will hit about 125 times, though hit counts of nearly 200 are possible.
• The Sparrow Factory counts as a summoned unit for Mecha Generator. The individual Sparrows do not.
• Only the first hit of each Sparrow will provide hitstun in PvE. In PvP, none of the hits apply any hitstun.
• The skill can easily attack enemies across the entire map, though it needs at least one enemy nearby for the Sparrows to start tracking in the first place.
• If this skill is reused while the first factory is still active, the first factory will be destroyed.
