Do Turbo's stats matter?

Attack, regen and break numbers on Turbo change nothing, so don't spend resources on them. Her core skill does the same job at any stat line, and her four basic attacks apply the same damage and break buff whatever she rolls. Put her investment into defence, which keeps her on the field long enough to hand those buffs out.

The same goes for which Turbo you keep. A higher attack or break stat on a Prismana or Alpha catch doesn't make her abilities stronger. If you're comparing two Turbos, look at their defensive stats and ignore the rest.

What decides how well Turbo performs

Turbo is a pure Support Aniimo and one of the top supports in the game, alongside Besauce. Her value comes from timing. The Irisalis team rotation opens with her, because her four basic attacks put her damage and break buff on the target. Her core skill has an 18-second cooldown, so if you switch to Infergon and want it again, you wait. In the recommended dark team she sits beside Pawney as main DPS, Infal Lupa for break and Glacy as healer.

Gear is less settled than stats. The Irisalis team needs no specific enhancement or held item on her. The Heritage Amulet suits her because her ability scales off HP, and the Lightning Needle is also given as the recommended item. In a pure support role she can run without a held item at all.

Getting a Turbo to use

Turbo lives in Nimbus Fields, an early zone near the first outpost, and you can catch her directly by fighting her. Early in the story you're given an Annipod Ultra at the start of the Alpha Turbo fight, and it guarantees the capture. Prismana Turbo spawns in Nimbus Fields during Prismana weather, at her flower teleporter location.

Not settled: The Heritage Amulet is recommended because Turbo's ability scales off HP, which sits awkwardly with her abilities being flat values. How much HP actually changes her output is not settled.
