Story missions

This article has an associated guide here. This page outlines how to achieve all the endings and their rewards.

Missions that advance the main story. The enemies you face will grow stronger in accordance with your level.

Story missions are the main story of Phantasy Star Portable 2 Infinity. As the name implies, they may only be played in story mode, and partner characters cannot be taken with the player, as story missions require the participation of specific partner characters, who will automatically be added to the party. There are different story missions available, depending on if the player enters episode 1, or episode 2.

Initially, the player will only have access to the current story mission, and must clear them in order. It is possible a story mission is not available, and in this case, the player must follow the instructions in the story progress tab in the main menu, which may range from meeting a certain character on Clad 6, or clearing an open mission.

After clearing all story missions for an episode, story missions may be replayed in any order at any time, with the exception of Chapter 10 - Act 2, and Chapter 10 - Act 3 in episode 1, which must be cleared from Chapter 10 - Act 1.

Story missions are an important aspect of the game, as clearing story missions is required to unlock other content, such as open missions, tactical missions, clothes/parts, stock in the Battle Shop, among other things. Therefore, it is recommended that players look to clear all story missions as soon as possible.

Mechanics

Story missions are unique in that creatures in the missions will scale to the player's level, to a limit. This means that playing other missions to level up will not necessarily give the player an advantage in clearing the story, unless the player outlevels the maximum creature level for the mission.

Upon completing an act, the player will be given a choice to return to Clad 6, or proceed to the next act if available. If the player chooses to continue to the next act, their player status will remain the same as at the end of act 1, including HP, blast gauge, and current NPC behaviour. They will also keep any effects accumulated on their weapon if applicable, such as Rengokuto Ensa's extra ATK from defeating creatures.

If a player is incapacitated at the final room of a story mission, on any subsequent attempts of the mission, they may choose to restart from the final room instead of replaying the entire mission again. However, clearing a mission using this method will automatically drop the mission evaluation to C rank.
