How do you do trio appeals and extreme bursts? For a while I could do the latter, but suddenly stopped being able to do that.
Also, is there a site like imas2.wota.info for Platinum Stars yet? Might be handy to have a lot of translated info hanging around.
There's a Pastebin, anyway.
http://pastebin.com/Wa3ApYbMFor multi-idol bursts, you need an outfit that allows it, first off. It'll have an effect written as デュオバースト for Duo Bursts(assuming you can't read Katakana, apologies if you can), トリオバースト for Trio Bursts, and クインテットバースト for Quintet Bursts. Duo Bursts require at least the effect チャージ Lv1 which is charge level 1, Trio Bursts require at least チャージ Lv2, and Quintets need to have チャージ Lv3. Thing is though, Trio Bursts require both charge level 1
and 2, and Quintet Bursts need all 3. You generate these charge levels during lives by successfully doing memory appeals with X when they show up. Side note, the number of hearts your leader has is also the number of appeals you can do during a live. And as far as I know, Extreme Burst doesn't mean much in the way of the number of idols involved.
For multi-idol appeals, you need to have either ドライブデュオ, ドライブトリオ, or ドライクインテット, which are Drive Duo, Trio and Quintet respectively. They make it so your appeals include the number of idols they list. They're simply for more points, though. So basically the reason you can't do them any more is you aren't using an accessory that allows you to, that's all.
