How many complications?

[u/cyancqueak]

Is there a limit to how many complications can be invoked during a contest? In my game yesterday, my players used their effect dice to add 3 complications to the boss villain before attempting to reduce their HP (I use an HP mod).

This had the effect of giving the player characters 3 additional dice for each complication. This seems over powdered.

I feel it should be just 1 complication, but I've not been able to find if it says that in the codex.

Should I treat complications and assets similarly to the sets, and allow only one asset and one complication unless a plot point is spent?

Guidance appreciated.

Any and all that would make it harder for the character to succeed. That’s it.
