Being at a type disadvantage means you’ll deal hardly any damage, and take quite a lot in return. The battles use a paper-scissors-rock system with character types. I found the combat to be mostly painless, and that’s primarily because it is quite basic. Lim does view some slideshow-esque flashbacks to remind people of what happens during these stories, as each trip to Memoria only covers part of the events for each arc, but it’s not quite adequate for the uninitiated. For those potentially interested in One Piece, Odyssey isn’t really a good way to get into it, because even if you don’t mind spoilers and knowing arc plot points well ahead of time, the minor differences that occur in Memoria may just well confuse you. Personally, I find it difficult to recommend One Piece Odyssey to those who aren’t already fans of the series, and not just because it’s a mostly bland RPG. For One Piece fans, you’d know that the crew temporarily splits up around that part of the story, so it technically doesn’t cleanly fit anywhere. It at the very least is after Dressrosa, but based on some things Sanji says it could almost be after Whole Cake Island, if it weren’t for a missing crew member. In terms of where this story sits in the One Piece timeline, Odyssey is basically like most of the films - in that it isn’t actually canon and only exists somewhere between arcs where it could never make perfect sense. Though the events in these memories aren’t always exactly the same as what actually happened in the past. The crew soon fights the island guardian Collossi and travels to Memoria, dream-like lands made out of their collective memories in order to regain their scattered powers. Shipwrecked, a strange girl called Lim separates the pirate crew from their powers, which is represented in this RPG framework by being set back to level one and having very few skills. Captain Luffy of the Straw Hat Pirates spots a strange island and demands they land there, before being pulled in by a storm. The setup, and story overall, is pretty basic.
