HP and attack include the magnification. Identical spawn lines are merged (2×7 = seven lines that each spawn 2).

Spawn timeline

Scroll sideways to see more. The number under each enemy is when it appears (seconds).

An estimate using the game's spawn rules. Ranged intervals use the midpoint, and the on-screen enemy limit is ignored, so when many enemies pile up they appear later than shown.

Clear rewards

If the reward chances add up to more than 100, the rows are rolled in order and each later row shares what is left.

Score rewards

Earned when your battle score reaches that value.
