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.
