What (if any) is the nuyen cost to reducing a drones star by 1?

Does Body have it's own price?

[PiXeL01]

It’s free to downgrade any stat on a drone, even body.

Just remember you can only get a single mod point totally.

Body is also the only stat you cannot increase.

[Rooks]

you can only get one mod stat point per each down grade (accel speed bod armor) or one total

Was that a question, Rooks?

You can only get back 1 Mod Point total. "no matter how many Downgrades you make, you only receive a single extra Mod Point."

Also, notably, reducing Armor takes 3 points to get the Mod Point. And the lowest a stat can go is 1 (except Speed, you can reduce that to 0).

EDIT: Oh, and you don't want to do this to reduce Body, because that would technically reduce the number of Mod Points you have to begin with. Reducing Body falls under the rules given in Attribute Modifications (Hint, it gives the ability to reduce Body by up to half for a net gain of 1 MP per Body lost).
