Completion spans the story, the optional bosses and a fully mastered build — a satisfying blend of narrative, exploration and combat mastery.
The checklist
- Finish the main story (and see the endings).
- Defeat the two Axons and the optional superbosses.
- Master a wide spread of Pictos into Luminas.
- Recruit and build all six party members.
Cleanup tips
- Sweep optional zones for Pictos and gear as you go — backtracking later is slower.
- Master Pictos into Luminas during normal play so completion is mostly done by endgame.
- Check whether endings require separate playthroughs or a late save before the final choice.
- Leave the superbosses until your builds and defence are fully online.
Endings & playthroughs
Expedition 33 has multiple endings tied to a late choice. Before the point of no return, make a manual save so you can see different outcomes without a full replay, and check a spoiler-light guide for exactly when that choice lands. Most of the rest of completion — Axons, superbosses, mastered Luminas — you'll finish naturally by exploring thoroughly as you go.
The list, and what you can really lose
56 trophies: 48 bronze, 5 silver, 2 gold and the platinum. Difficulty does not
gate any of them — you can play on the easiest setting, with the accessibility options on, and still earn every
one.
Five trophies are missable. Two depend on the prologue, one on an
optional camp scene in Act 2 and one on a dialogue choice in Act 3. The fifth only needs a boss you can leave
for later:
- Follow the Trail — before patch 1.5.0, missing the Old Key at the prologue festival locked you out of one Journal (see the note below for where the patch puts it back);
- A Peculiar Encounter — skip the optional Mime fight earlier in the prologue and New Game+ or a new save is the only way back;
- Connoisseur — needs 33 Records; miss both the prologue Mime's Record and the Act 2 camp scene with Verso and Maelle (unlocked after the first Axon) and you fall one short;
- Professional — beat any boss without taking damage. It is only missable in theory, because Chromatic enemies count and there are many of them. To be safe, leave the optional Chromatic Lancelier in Spring Meadows (or another early Chromatic enemy) and beat it during cleanup at the end;
- Maelle — her Level 7 relationship interaction, available from Act 3, offers Truth or Lie. Pick Lie and you get neither the trophy nor her final Gradient attack, so pick Truth. If you pick wrong, reload an earlier autosave right away: the game has no manual saves and rotates through 21 autosave slots.
Patch 1.5.0 softened one of them. If you missed the Old Key in the prologue it now
reappears in the final area — up the first steps from the docks, on the left. Worth knowing before you restart a
run over it, and worth checking your patch version before you trust it.
Still to verify
Cross-checked on 5 September 2026 against PowerPyx and Game8 — which agree on the 56/48/5/2 breakdown and that difficulty does not gate trophies. Both also confirm patch 1.5.0 added the Old Key back near the docks in the final area, matching what this page already said. Updated on 23 September 2026 from PowerPyx's trophy guide and roadmap: this page previously said only the prologue's Old Key and Mime were missable; PowerPyx lists five missable trophies (Follow the Trail, Maelle, Connoisseur, Professional, A Peculiar Encounter) and describes a real Act 3 point of no return — the Maelle relationship's Level 7 Truth/Lie choice — that this page did not mention at all. Not from a playthrough: nobody here has played it, and what the sources do not describe is not on this page.
