How to get Siren

  1. Open the DLC content

    Own and install Risen Ballbylon and complete the base game. Water is a new DLC base ball. Charm is a base-game ball. Check DLC access →

  2. Get both ingredients to level 3

    Obtain Water and Charm when offered in your run. Choose each ball again in level-up upgrades until both are level 3. Merely holding both balls is not enough.

  3. Select Siren at a Fusion Reactor

    Pick up a Fusion Reactor when one drops and choose the Siren Evolution. Look for the exact target name rather than trying to create a regular mixed fusion. The finished ball should be named Siren.

Plan from the balls you currently hold →

What Siren does

Passes through enemies. Each hit has a chance to charm the enemy for a few seconds.

Use & limits

A hit can fail to charm, and a successful charm lasts only a few seconds. Piercing does not turn the chance into a guaranteed control effect on every enemy.

When to choose it

Choose Siren when you want piercing shots with chances to apply brief charm along their path. Allow for both an unsuccessful charm roll and the short duration when deciding whether it supplies enough control.

If the Evolution is missing

Check the exact ingredient pair and both current levels. A recipe sharing one ingredient is a different target: check that both selected names match Siren’s pair. If an ingredient has not appeared, it is still missing; no fixed drop time, minimum reactor count or guaranteed offer is implied.

If its effect looks different

An enemy that was hit but not charmed can be a normal chance outcome. A previously charmed enemy returning to normal after a few seconds is also consistent with the effect.
