Overview
Strategy
Due to the nature of RoPoChi being a mix of all the co-op bosses, it thankfully misses out on most of the deadliest cards and passives of each individual boss. The passive you mostly have to worry about is the added dice rolls per minion alive on the field, as this gives it high attack rolls constantly especially with the Big Poppo minion taking a while to take down. However, because it gains -2 ATK per minion as well, high-HP Avengers like Poppo can survive a hit even with 1-2 minions and hit back with Avenger-boosted ATK.
Most of RoPoChi's Level 1-2 cards serve merely as annoyances, usually either stealing stars or buffing the minions to make them harder to take down. Because your stars get frequently stolen, it may be advisable to try and gain normas via Wins. Make sure the Attacker is kept healthy as it attempts to take out Chicken minions and stepping on the many red panels to try and work their way up to Norma Level 4.
Among the level 2 cards, the most dangerous is Delusional Numbers, which allows it to roll natural 7s if you're unlucky. If you're lucky, it will roll 0s. One way you can take advantage of this is if RoPoChi rolls a 0 in a battle, it will keep rolling 0s for that battle, making you free to hit it at that point, but you have to weigh the risk of it also just rolling all 7s instead.
The Level 3 cards are what makes RoPoChi excessively dangerous. Once it starts drawing the high-level cards, your team must pay attention to the next card in play and react accordingly:
Poppo Universe - The player that moves latest with Party TIme should use the card.
Poppo Care - Keep everyone alive regardless of HP.
Refined Talons - Have only one player with as low HP as possible. A mix of Guardians and Avengers can help keep this card from doing too much damage.
Beak of the Demi-Bird - Stay away as much as possible from the boss, use Dash and Here and There cards if the player is too close to RoPoChi.
Big Po's Special - This lasts for 2 turns. Keep finding ways to heal and reduce outside damage such as Dinner cards, Metallic Monocoque cards, and Guardian's Protect.
Another special way to reduce the extra damage RoPoChi does is to keep its star count low. It has multiple cards that use stars, and if you're able to dodge its other cards which steal or gain stars, RoPoChi can easily fall under 100 stars, rendering it unable to use certain expensive cards and greatly reducing the damage Poppo Universe will deal.
