HP and attack include the magnification. Identical spawn lines are merged (2×7 = seven lines that each spawn 2). Enemies with a base HP condition start appearing once it is met.

Spawn timeline

Scroll sideways to see more. The number under each enemy is when it appears (seconds). For enemies with a base HP condition, move the slider to set when the condition is met.

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.
