Dressrosa. All strawhat strategies are successful. This one is rather vague but not too hard to figure out. The most difficult portion is early on. Your goal is to get Ceasar Clown to the drop point, but also prevent Bellamy's group from taking advantage while your're gone. So take care of the mission-based captains in the town, all the while spending a bit of time supporting Law. All 4 captains in town must be defeated before Bellamy appears, and he must be defeated before he retreats or Caesar arrives with Law at the Spot. If you succeed, you will get a green "objective success" message jsut before Doflamingo appears. If not, you will get a red "objective failed" message instead.
A few other actions that may affect this Dressrosa mission:
-Going into the collosseum with Law
-Preventing all allies from retreating (against their will). This includes Bellamy who appears aftter Fujitora & Doflamingo appear on Green Bit
-Preventing the Blackbeard captains from taking the territory to the south
-When Kuzan becomes a support, use him to destroy all snail-phone booths marked with a (!). I'm more or less certain this one is manditory
- It seems with the Dressrosa 9th puzzle piece, you also have to make sure Bellamy isn't defeated when he reappears surrounded by enemies and make sure you finish off the REAL Doflamingo, not his clones. I'll add that to my list shortly.
- Help conquer the Smile Factory before beating Fujitora and Kizaru
- Conquer the Territory where Fujitora starts
- Conquer the Territory where Burgess starts
- Conquer the Territory where Blackbeard starts
- Conquer the Territory at the Left Top over the Spot for Caesar.
