Siren Spire

Where to catch the Siren Spire

The Siren Spire lives in Nuclear Wasteland (zone 17 of 17), around the middle of the zone. It is number 4 of 8 in the Nuclear Wasteland index. A full-strength throw needs roughly 6,500 – 7,000+ Throw Power to land in Nuclear Wasteland.

Foods that land here: Toxic Donut (~1 Td), Mutant Melon (~20 Td), Atomic Pizza, Uranium Cake (~9 Qad). A higher-tier food pushes the roll toward the rarer end of the Nuclear Wasteland list, so the newest food you own is always the best bait.

Any throw that lands around the middle of the zone can produce it. If you are hunting it for the index, lower your throw strength with the gear icon until the food lands on that spot – distance inside a zone decides which animals can come.

Is it worth keeping?

• A plain Siren Spire earns 800000x a plain Wraith, the best animal from Phantom Harbor.
• Keep it longer only if it rolled a strong mutation or size (see the table below) or you need it for the index.

Siren Spire income by mutation and size

A plain Siren Spire makes $6.4Dd/s. Mutations and sizes multiply that number, and the two stack. The table below multiplies the plain income by the multipliers I have measured (Gold ×1.5, Diamond ×3, Emerald ×5, Ruby ×10, Rainbow ×20; Big ×2, Large ≈×4.3, Huge ≈×9, Colossal ≈×18.5, Gigantic ≈×37). Treat the size columns as estimates – real catches land a little above or below. With the 2x Cash gamepass every number doubles.
