Duo/trio appeals?

[violetmythmaker]

Okay, I'm having a bit of trouble finding any information on these in the larger thread, so...how exactly do you use these skills once your idols have them unlocked? I take it these are just like using an appeal in S4U when you see 2 or 3 idols on screen at once?

If you're talking about Duo/Trio Memory Appeals, those trigger on consecutive uses of memory. As for Duo/Trio Bursts, you need to use a Memory Appeal once or twice when your voltage is full for either Duo or Trio Bursts, respectively.

Is it enough if one idol has the respective duo/triple skill or do all idols involved in it need the skill?

One is fine.
When you set up your unit (in screens that allow you to do so) there's three boxes on the right side of the screen which denote what that idol setup will enable you to do. First box is Memory Appeal limit ("-"/Duo/Trio), second box Burst Appeal limit (see Memory Appeal), third is Burst counter (a festival-relevant skill that all idols can access, just a simple "-" or "O")
