Does this ruin my S.O.S chain?

Question

So, I'm trying to shiny hunt a Stuffel, and it uses brutal swing on everyone in the field also KOing a Stuffel. Does that break the chain or does that keep going?

Answer 1

It does not break your chain

As long as you still have a stufful on the field you have not broken your chain. But lets say you were hunting pichus and it called in happiny and then you ko'd pichu, your chain would end because happiny won't call for help. But a stufful being ko'd from brutal swing does not end your chain
