QUICK ANSWER

The completion route contains 8 base-game Blades, 37 Artefacts, 30 Charms including 5 Theseus' Echoes, and 200 Resonance Points. You need at least 165 points in one playthrough for all skills.

The verified totals

PowerPyx counts 275 trophy-related collectible locations: 8 Blades, 37 Artefacts, 30 Charms and 200 Resonance Points. The optional preorder Blade raises the weapon inventory to nine but is not required for the Plunderer trophy.

The five Theseus' Echoes reward Pierced Coins that are counted among the 30 Charms, so do not add them again when checking the overall total.

The save rule that matters

Resonance Points are saved when you reach the next checkpoint. If you die before that checkpoint, collect the pickup again. Replaying a chapter restores the point count from the first time you reached it, so it cannot be used to carry a later total into an older section.

All other collectible categories keep their progress through Chapter Select. After picking up a missed regular collectible, PowerPyx says you can return to the main menu and it still counts.

Chapter-by-chapter collectible totals

Use this table before leaving a chapter. The Charm column already includes any Pierced Coin obtained from a Theseus' Echo in that chapter.

A zero means the chronological source route records none of that category in the chapter; it is not a missing tracker entry.
